On the evening of January 15, 2006, Jonathan Dalton, Latango Robertson and [Mr. Simpson] decided to go to Fritzi's hip hop club in Oklahoma City. Prior to going to the club, the three drove in [Mr.] Dalton's white Monte Carlo to [Mr. Simpson's] house so that [Mr. Simpson] could change clothes. While at his house, [Mr. Simpson] got an assault rifle[,] which he brought with him.1 Before going to Fritzi's, the men first went to a house party where they consumed alcohol and marijuana. When they left the party, [Mr. Simpson] put the assault rifle into the trunk of the Monte Carlo, which could be accessed through the back seat.
The three arrived at Fritzi's between midnight and 1:00 a.m. on January 16. Once inside, they went to the bar to get a drink. [Mr. Simpson] and [Mr.] Dalton also took a drug called "Ecstasy." After getting their drinks, [Mr.] Dalton and [Mr.] Robertson sat down at a table while [Mr. Simpson] walked around. When [Mr. Simpson] walked by London Johnson, Anthony Jones and Glen Palmer, one of the three apparently said something to him about the Chicago Cubs baseball cap that he was wearing. [Mr. Simpson] went back to the table and told [Mr.] Dalton and [Mr.] Robertson that some guy had given him a hard time about his cap. At some point, [Mr. Simpson] approached [Mr.] Johnson, [Mr.] Jones and [Mr.] Palmer again. During this encounter, [Mr. Simpson] told them that he was going to "chop" them up.2 After making this threat, [Mr. Simpson] walked away. He returned a short time later and walked up to Palmer.
*558[Mr. Simpson] extended his hand and said, "We cool." [Mr.] Palmer hit [Mr. Simpson] in the mouth knocking him to the floor. [Mr. Simpson] told [Mr.] Dalton and [Mr.] Robertson that he wanted to leave and the three of them left the club.
Out in the parking lot, [Mr. Simpson], [Mr.] Dalton and [Mr.] Robertson went to [Mr.] Dalton's Monte Carlo. Before leaving, they talked with some girls who had come out of the club and were parked next to them. The girls told the men to follow them to a 7-[Eleven] located at NW 23rd Street and Portland. When they arrived at the store, [Mr. Simpson], [Mr.] Dalton and [Mr.] Robertson backed into a parking space toward the back door and the girls pulled in next to the pumps. While the men were sitting in the Monte Carlo, they saw [Mr.] Johnson, [Mr.] Jones and [Mr.] Palmer drive into the parking lot in [Mr.] Palmer's Chevy Caprice. They recognized [Mr.] Palmer as the person who had hit [Mr. Simpson] at Fritzi's. [Mr.] Dalton told [Mr. Simpson] to "chill out" but [Mr. Simpson] was mad and wanted to retaliate against [Mr.] Palmer. When [Mr.] Palmer drove out of the parking lot onto 23rd Street and merged onto I-44, [Mr. Simpson] told [Mr.] Dalton to follow them.
While they were following the Chevy, [Mr. Simpson], who was sitting in the front passenger seat, told [Mr.] Robertson, who was sitting in the back seat, to give him the gun. He told [Mr.] Robertson that if he had to get the gun himself, there was going to be trouble. [Mr.] Robertson reached through the back seat into the trunk and retrieved the gun for [Mr. Simpson]. [Mr.] Dalton followed the Chevy as it exited the interstate onto Pennsylvania Avenue. He pulled the Monte Carlo into the left lane beside the Chevy as they drove on Pennsylvania Avenue and [Mr. Simpson] pointed the gun out his open window and started firing at the Chevy.
When the Chevy was hit with bullets, [Mr.] Palmer was driving, [Mr.] Jones was sitting in the front passenger seat and [Mr.] Johnson was in the back seat. [Mr.] Johnson heard about twenty rapid gun shots and got down on the floor of the car. He did not see the shooter but noticed a white vehicle drive up beside them. The Chevy jumped the curb and hit an electric pole and fence before coming to a stop. [Mr.] Palmer and [Mr.] Jones had been shot. [Mr.] Jones had been shot in the side of his head and torso and was unconscious. [Mr.] Palmer had been shot in the chest. He was initially conscious and able to talk but soon lost consciousness when he could no longer breathe. [Mr.] Johnson tried to give both [Mr.] Jones and [Mr.] Palmer CPR but was unsuccessful. He flagged down a car that was driving by and asked the driver to get help. Both [Mr.] Palmer and [Mr.] Jones died at the scene from their gunshot wounds.
After he fired at the Chevy, [Mr. Simpson] said, "I'm a monster. I just shot the car up." He added, "They shouldn't play with me like that." [Mr.] Dalton kept driving until they reached a residence in Midwest City where he was staying. They dropped the gun off and switched cars, and then [Mr.] Dalton, [Mr.] Robertson and [Mr. Simpson] went to meet some girls they had talked to at Fritzi's.

Simpson v. State (Simpson I ),
B. Procedural History
1. State Court Proceedings
a. Criminal trial and sentencing
The State of Oklahoma charged Mr. Simpson with the first-degree murders of *559Glen Palmer and Anthony Jones and with discharging a firearm with intent to kill London Johnson.
Prior to trial, Dr. Phillip Massad, a clinical psychologist, evaluated Mr. Simpson's mental condition. Mr. Simpson disclosed to Dr. Massad that, when Mr. Simpson was sixteen years old, a friend ambushed and shot him for refusing to kill a government witness scheduled to testify in the friend's criminal trial. Mr. Simpson suffered five gunshot wounds and spent two months hospitalized and comatose. Even after his release from the hospital, Mr. Simpson was readmitted frequently for treatment of complications arising from infections. He endured sixteen surgeries over a seven-month period, and feared his attackers would return to kill him. Dr. Massad concluded Mr. Simpson suffered from Post-Traumatic Stress Disorder (PTSD) as a result of the shooting.
Mr. Simpson's counsel notified the court he intended to present evidence of Mr. Simpson's PTSD and to call Dr. Massad as an expert witness on that topic. The defense planned to elicit testimony from Dr. Massad that Mr. Simpson suffered from PTSD and that this condition affected his ability to form the intent of malice aforethought required for a first-degree murder conviction. The State moved to exclude Dr. Massad from testifying at the guilt stage of trial. At a hearing on the matter, defense counsel represented that Dr. Massad would testify it was "possible that the PTSD affected [Mr. Simpson] to the extent that he was not able to form the specific intent" to kill, and that, because of his PTSD, Mr. Simpson would have "magnified in his own mind the threat" the victims presented. Trial Mot. Hr'g Tr. at 18 (Sept. 19, 2007). As the State notes, however, Dr. Massad's psychological report "never indicate[d] that [Mr. Simpson's PTSD] prevent[ed] him from forming an intent to kill" or from "know[ing] what he was doing was wrong." Id. at 11-12. The trial court granted the State's motion, holding that Oklahoma law precludes testimony that a defendant could not have formed the specific intent to commit a crime, except in the context of an intoxication or insanity defense, neither of which had been advanced by Mr. Simpson at that time.
The jury rendered its decision finding Mr. Simpson guilty of the first-degree murders of Mr. Palmer and Mr. Jones.4 In the ensuing penalty stage, the State alleged four aggravating factors it claimed warranted a sentence of death:
1. [Mr. Simpson], prior to the time of sentencing, was convicted of a felony involving the use or threat of violence to [another] person [ ("Prior Violent Felony Aggravator") ];
2. [Mr. Simpson] knowingly created a great risk of death to more than one person [ ("Risk of Multiple Deaths Aggravator") ];
3. The murder was especially heinous, atrocious, or cruel [ ("HAC Aggravator") ];
4. At the present time there exists a probability that [Mr. Simpson] would commit criminal acts of violence that would constitute a continuing threat to society [ ("Continuing Threat Aggravator") ].
*560Trial R. vol. 1 at 44. Mr. Simpson asserted three factors in mitigation: (1) his age,5 (2) his mental state (PTSD diagnosis), and (3) his family support.
i. Aggravating evidence presented at sentencing
The State moved to incorporate all the evidence presented during the guilt stage and-after determining the evidence would be relevant to the HAC Aggravator, the Continuing Threat Aggravator, and the Risk of Multiple Deaths Aggravator-the court granted the motion.
In addition, Mr. Simpson stipulated that he had previously received a seven-and-a-half-year prison sentence for armed robbery, and the victim of that crime, Hung Pham, appeared in support of the State's case in aggravation. Mr. Pham testified that Mr. Simpson and two other men forced themselves into Mr. Pham's home at gunpoint. Mr. Pham provided compelling details, stating that Mr. Simpson shoved the gun in Mr. Pham's face, forced him inside, and beat him in the face and back with the gun. After taking Mr. Pham's wallet, Mr. Simpson pulled Mr. Pham into a bathroom closet, forced him to kneel on the floor, and demanded all of his money. When Mr. Pham replied that he did not have any more money, Mr. Simpson shot Mr. Pham in the head and left with Mr. Pham's wallet. Mr. Pham remembers the encounter vividly, "[b]ecause ... [Mr. Simpson] hit my face, everything, he hurt me a lot. I remember forever." Trial Tr. vol. 7 at 96-97.
The State also relied on the testimony of Roy Collins, a jailhouse informant who had temporarily shared a cell with Mr. Simpson. Hoping to leverage a deal with the district attorney's office for his own early release, Mr. Collins asked Mr. Simpson about the murders. Mr. Collins testified that Mr. Simpson admitted to the altercation at Fritzi's, seeing the victims at the 7-Eleven, following them, and then firing the assault rifle into their car. Mr. Collins further stated that Mr. Simpson expressed no remorse for the murders and even tried to hire Mr. Collins to kill Mr. Johnson, the surviving victim, and to assault two pregnant women listed as State witnesses. Mr. Collins also testified that Mr. Simpson would smile and laugh when talking about the murders and that Mr. Simpson thought he was a "gangster[ ]" like "Tupac or Biggie Small." Id. at 47. Mr. Collins reported that Mr. Simpson "couldn't believe the victims' families were crying" because, according to Mr. Simpson, the victims "were gangbangers, that's the life they lived, that's the life they chose." Id. at 54-55. Mr. Collins also indicated that he could tell Mr. Simpson was a member of the Bloods gang because "[h]e's got red ink all over his neck." Id. at 58-59.
Finally, the prosecution presented victim impact statements from Rosalind Jones, the mother of Anthony Jones, and Tiarra Palmer, the sister of Glen Palmer.
ii. Mitigating evidence presented at sentencing
The defense called six witnesses in mitigation: Dr. Massad, to testify about Mr. Simpson's PTSD diagnosis; Evan Gatewood, to impeach Mr. Collins; and Mr. Simpson's mother, grandmother, aunt, and ex-girlfriend, to testify about Mr. Simpson's upbringing and family support. The vast majority of the mitigating evidence focused on the ambush and shooting of Mr. Simpson and his long road to recovery. The witnesses indicated that family members visited Mr. Simpson every day in the hospital and that his mother believed "[h]e was on his dying bed." Id. at 153.
*561Dr. Massad testified that Mr. Simpson reported being "paranoid hostile" and hypervigilant as a result of having been shot. Id. at 190-92. Dr. Massad also testified at length about the basis of his diagnosis that Mr. Simpson suffered from PTSD and about the typical symptoms of the disorder. He explained that people suffering from PTSD "might be hypersensitive and overreact" to common situations. Id. at 166. Additionally, such a person could be "hypervigilant," constantly on "alert and watchful for danger," and could experience "exaggerated startle response[s] and other symptoms." Id. at 167. Dr. Massad further opined that drugs or alcohol could exacerbate this hypersensitivity and paranoia because they can "increase the likelihood that [a person] would react or overreact." Id.
Mr. Simpson's aunt highlighted examples of this paranoia and hypersensitivity in her testimony, noting Mr. Simpson was constantly terrified the men who had shot him would return and finish the job. He was "paranoid and scared" to the point he refused to open the door when people came to visit, and he moved out of his mother's house because it was too close to the site of the shooting. Id. at 205-06.
Most of the testimony from Mr. Simpson's family focused on the family's love and support of Mr. Simpson. They gave limited detail about his childhood, characterizing him as a good child with a relatively normal upbringing. There was also testimony that Mr. Simpson's grandmother was primarily responsible for raising him, while his teenaged, single mother was finishing high school. The witnesses reported that Mr. Simpson's father was not involved in his upbringing and that Mr. Simpson dropped out of school in the eighth grade. The overall theme of the testimony was that Mr. Simpson had a good family who loved and supported him, but could not provide all the guidance required in raising him and his two siblings. Mr. Simpson's grandmother, mother, aunt, and ex-girlfriend all testified they would continue to support Mr. Simpson and would visit him in prison, if his life was spared.
Following the sentencing trial, the jury found all four aggravating factors by special verdict and recommended a sentence of death for each murder. The court adopted the jury's recommendation and sentenced Mr. Simpson to death.
b. Appellate and post-conviction proceedings
Mr. Simpson appealed his convictions and sentences, alleging a variety of errors in both the guilt and sentencing stages of his trial. On direct appeal, the OCCA affirmed Mr. Simpson's convictions and death sentences as to both Mr. Palmer and Mr. Jones. Simpson I ,
Simultaneous with his direct appeal, Mr. Simpson filed an application for post-conviction relief and an application for an evidentiary hearing on whether he had received ineffective assistance of trial counsel. Simpson v. State (Simpson II ), No. PCD-2007-1262 (Okla. Crim. App. Oct. 13, 2010) (unpublished). The OCCA denied both applications.
Three years later, Mr. Simpson filed a second state application for post-conviction relief, coupled with another application for an evidentiary hearing, in order to exhaust claims presented in his federal habeas petition. Again, the OCCA denied both applications.
*562See Simpson v. State (Simpson III ), No. PCD-2012-242 (Okla. Crim. App. Mar. 8, 2013) (unpublished).
2. Federal Court Proceedings
Mr. Simpson sought federal post-conviction relief by filing a petition for a writ of habeas corpus pursuant to
II. STANDARD OF REVIEW
AEDPA requires that we apply a "difficult to meet and highly deferential standard" in federal habeas proceedings under
(1) resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States; or
(2) resulted in a decision that was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.
Section 2254(d)(1) 's reference to "clearly established Federal law, as determined by the Supreme Court of the United States," "refers to the holdings, as opposed to the dicta, of th[e] Court's decisions as of *563the time of the relevant state-court decision." Williams v. Taylor ,
Under § 2254(d)(1), a state-court decision is "contrary to" the Supreme Court's clearly established precedent if it "applies a rule that contradicts the governing law set forth in [Supreme Court] cases" or if it "confronts a set of facts that are materially indistinguishable from a decision of th[e] Court and nevertheless arrives at a result different from [that] precedent." Williams ,
A state-court decision is an "unreasonable application" of Supreme Court law if the decision "correctly identifies the governing legal rule but applies it unreasonably to the facts of a particular prisoner's case." Williams ,
Claims not "adjudicated on the merits" in state court are entitled to no deference. Fairchild I ,
With these standards in mind, we turn to Mr. Simpson's claims.
III. DISCUSSION
As discussed, Mr. Simpson raises seven grounds for relief. We consider each of his arguments in turn.
*564A. Right to Present a Complete Defense
Mr. Simpson first asserts he is entitled to federal habeas relief with respect to his convictions because the trial court erroneously excluded expert testimony regarding his PTSD diagnosis and dissociative episodes from the guilt stage of trial. Mr. Simpson claims Dr. Massad's testimony was necessary to support the defense that his PTSD, standing alone or in conjunction with his intoxication defense, rendered him incapable of forming the specific intent to kill. According to Mr. Simpson, excluding this evidence violated his constitutional right to present a complete defense.
We begin our review of this claim by providing additional factual and procedural background. We then address the State's arguments that the claim is unexhausted and unpreserved.8 Deciding that the PTSD portion of Mr. Simpson's claim is properly preserved and has been exhausted, we then examine the OCCA's merits decision. We conclude that decision is not unreasonable under § 2254(d)(1), and we therefore deny Mr. Simpson relief on this claim.
1. Additional Factual and Procedural Background
In reviewing this claim, the OCCA examined the transcript of the trial court hearing on the exclusion of the evidence and Dr. Massad's testimony during the sentencing stage of Mr. Simpson's trial. The OCCA concluded the trial court did not abuse its discretion by excluding this testimony from the guilt stage of trial because Dr. Massad could not say how Mr. Simpson's PTSD affected his ability to form the intent to kill. Simpson I ,
On federal habeas review, Mr. Simpson challenges the OCCA's determination as both contrary to and an unreasonable application of clearly established federal law. The State counters that Mr. Simpson is barred from presenting this claim because he has failed to exhaust available state court remedies, he has forfeited the argument he makes on appeal by not presenting it to the district court, and, alternatively, because the OCCA's decision was neither contrary to federal law nor unreasonable.
2. Exhaustion and Preservation
We begin our analysis with the state's argument that Mr. Simpson failed to exhaust his claim that the trial court violated his right to present a complete defense. See United States v. Miller ,
a. Legal standard
AEDPA permits federal courts to entertain only those applications for a writ of habeas corpus alleging that a person is in state custody "in violation of the Constitution or laws or treaties of the United States."
Turning to preservation, "[a] federal appellate court will not consider an issue not passed upon below." F.D.I.C. v. Noel ,
b. Analysis
Before this court, Mr. Simpson contends he suffers from dissociative episodes, and that his PTSD was the result of being shot by his friend and a lifetime of trauma. The State asserts Mr. Simpson's claim is unexhausted and unpreserved because he is presenting an entirely different theory to this court than the theory he presented to the OCCA and the district court. The State further asserts Mr. Simpson has improperly supplemented his argument on appeal by relying on facts raised in conjunction with his ineffective assistance of counsel claim. Mr. Simpson disagrees, stating, "his argument throughout has been that his PTSD, not malice aforethought, is what caused him to react the way he did." Aplt. Reply Br. at 3-5. He further contends his claim is supportable even without the additional facts about his violent upbringing, and that the evidence of dissociative episodes is not new because the description of the phenomenon, if not the name itself, was presented to the OCCA.
For purposes of discussion, we divide Mr. Simpson's argument into two categories: (1) PTSD evidence and (2) evidence of dissociative episodes. We conclude that Mr. Simpson properly preserved and exhausted his PTSD argument, but that he failed to properly preserve his argument concerning dissociative episodes.
i. PTSD evidence
On direct appeal, Mr. Simpson argued his PTSD was the result of a single *566event-his having previously been ambushed and shot by his friend. Mr. Simpson further claimed his PTSD was "relevant to the issue of whether he shot with malice aforethought, or did so out of a sense of exaggerated fear and terror caused by his PTSD," which was exacerbated by his consumption of drugs and alcohol on the night of the murders. Aplt. Br. at 22-23, Simpson I ,
Although Mr. Simpson's position in this court is more refined than the argument he made to the OCCA, the core of his PTSD claim is the same. His assertion that the OCCA's decision was "unreasonable based on [the OCCA and trial court's] misunderstanding of PTSD" is not a new claim, but rather an attempt to bolster his consistently-advanced position that his PTSD diagnosis was relevant as a defense during the guilt stage of trial. Compare Aplee. Br. at 14-29, with Simpson I ,
The State also asserts that Mr. Simpson has failed to preserve this claim on appeal by failing to raise it in the district court. The district court described Mr. Simpson's PTSD argument as follows:
In Ground 2, [Mr. Simpson] asserts that he is entitled to habeas relief because the trial court prevented him from presenting evidence in the guilt stage that he suffered from Post Traumatic Stress Disorder (PTSD). [Mr. Simpson] argues that this evidence was relevant to the issue of intent and his voluntary intoxication defense, and that because he was unable to present this evidence, he was denied his constitutional right to present a complete defense.
Simpson IV ,
ii. Dissociative episodes
In this court, Mr. Simpson also attempts to introduce a new defense related to, but qualitatively different than, the PTSD defense he raised before the district *567court. In his argument to this court, Mr. Simpson contends he "was in the midst of a PTSD and/or dissociative episode during the crime[, which] reveals his brain was functioning such that either he had a reduced capacity to form the specific intent of first-degree malice aforethought murder, or he was unable to form the intent at all." Aplt. Br. at 24. To be sure, Mr. Simpson argued to the district court that his PTSD, combined with his drug and alcohol abuse, prevented him from forming the requisite mens rea. See Aplt. Br. at 14, Simpson IV ,
3. Merits
We turn now to the merits of Mr. Simpson's assertion that the trial court violated his constitutional right to present a complete defense when it excluded evidence that his PTSD made him hypervigilant and, together with his substance abuse on the night of the murders, rendered him incapable of forming the requisite mens rea. See Crane v. Kentucky ,
a. OCCA decision
The OCCA rejected both of these arguments on direct appeal, finding Dr. Massad's testimony irrelevant in both situations because he "could not testify as to how [Mr. Simpson's] PTSD could affect his intent at the time of the crime." Simpson I ,
b. Reasonableness of the OCCA's legal determination
The Supreme Court has recognized that although criminal defendants have the right to present a complete defense, they must still comply with a state's well-established rules of evidence. See *568Holmes v. South Carolina ,
i. PTSD as a stand-alone defense
As relevant to Mr. Simpson's first argument-that PTSD negated specific intent-the trial court correctly noted that Oklahoma permits diminished capacity evidence only in the case of an intoxication or insanity defense. Frederick v. State ,
ii. PTSD as support for the intoxication defense
Alternatively, Mr. Simpson argues the trial court erred by excluding Dr. Massad's testimony because it was necessary to assist the jury in evaluating Mr. Simpson's intoxication defense. The OCCA held that, because Dr. Massad's testimony was irrelevant, the trial court did not abuse its discretion in excluding it. Simpson I ,
Under Oklahoma law, evidence is relevant if it "ha[s] any tendency to make the existence of any fact that is of consequence to the determination of the action more or less probable than it would be without the evidence."
A review of Dr. Massad's testimony fails to demonstrate any meaningful connection between PTSD and intent generally, or intoxication specifically. Even a generous reading of his testimony demonstrates only a bare assertion that Mr. Simpson had PTSD and that PTSD could cause one to be hypervigilant and to overreact to stimuli. Dr. Massad's testimony lacked any detail on the impact Mr. Simpson's PTSD had on his ability to form the intent to kill, and Dr. Massad's testimony on the interactive effects of PTSD and intoxicants is similarly lacking. Dr. Massad opined that PTSD could be affected by drugs and alcohol because they "could lower one's defenses and increase the likelihood that [the person] would react or overreact." Trial Tr. vol. 7 at 167. On cross-examination, however, Dr. Massad admitted he was "not sure about how the brain and alcohol interact" beyond generally lowering a person's inhibitions-which occurs regardless of "whether or not they have PTSD." Id. at 183. This is not the type of specialized knowledge beyond the "normal experiences and qualifications of laymen jurors." See Hooks III ,
Because a fairminded jurist could agree that Dr. Massad's testimony was irrelevant, the OCCA's decision was reasonable.
B. Brady Claim
Mr. Simpson next alleges the prosecutors violated their constitutional responsibility under Brady v. Maryland to disclose all evidence favorable to the defense. Specifically, he contends the prosecution suppressed impeachment evidence against a State sentencing-stage witness, Roy Collins.
In addressing this claim, we begin with a discussion of what Brady requires. We then provide additional background relevant to the OCCA's decision, concluding that the OCCA did not resolve this claim on the merits. Instead, the OCCA held that Mr. Simpson waived his Brady claim by not bringing it on direct appeal or in his first state post-conviction application. We next consider whether Mr. Simpson can overcome that state procedural bar and conclude he cannot. As a result, we affirm the district court's denial of relief on this claim. Finally, we consider Mr. Simpson's request for discovery and an evidentiary hearing before the district court and we deny relief on that request, as well.
1. Elements of a Brady Claim
We have recognized three essential elements of a Brady claim: (1) the prosecutor suppressed the evidence; (2) the suppressed evidence was favorable to the accused, either because it is exculpatory or because it is impeaching; and (3) prejudice ensued because the suppressed evidence was material. See Scott v. Mullin ,
Here, Mr. Simpson claims the State suppressed three pieces of evidence (collectively, the "Collins Evidence"):
(1) a video-taped interview with Roy Collins from January 5, 2006, which reveals Mr. Collins's Hoover Crips gang affiliation and calls into question the veracity of his testimony concerning Mr. Simpson's jailhouse statements by revealing that Mr. Collins made nearly identical jailhouse statements about Jason Whitecrow, a defendant in an unrelated criminal trial;
(2) Mr. Collins's complete arrest, conviction, and incarceration records that reveal an additional four convictions to which Mr. Collins did not testify at trial; and
(3) statements reflecting Mr. Collins's expectation of prosecutorial assistance in exchange for his testimony.
According to Mr. Simpson, the Collins Evidence was materially favorable Brady evidence that could have cast doubt on the credibility of Mr. Collins's testimony, which, in turn, was critical to support the Continuing Threat Aggravator. See Giglio v. United States ,
2. OCCA Decision
Mr. Simpson did not present his Brady claim to the OCCA until his second application for post-conviction relief. The OCCA held the claim was procedurally barred because the misconduct happened at trial, the legal basis for the claim was available on direct appeal and on the first post-conviction application, and "the factual basis for the claim[ ] was available and could have been ascertained through the exercise of reasonable diligence." Simpson III , slip op. at 4 (citing
3. Procedural Default
a. Independent and adequate procedural bar
Under the doctrine of procedural default, "[c]laims that are defaulted in state court on adequate and independent state procedural grounds will not be considered by a habeas court...." Fairchild II ,
In turn, a state procedural rule is independent "if it relies on state law, rather than federal law, as the basis for decision." Banks v. Workman ,
b. Legal background on cause and prejudice
"A prisoner may obtain federal review of a defaulted claim by showing cause for the default and prejudice from a violation of federal law." Martinez ,
Mr. Simpson must establish both cause and prejudice to overcome the state procedural bar, and we must reject his Brady claim if he fails to show either requirement. See McCleskey v. Zant,
We exercise our discretion to proceed directly to the prejudice/materiality question. Ultimately, we deny Mr. Simpson relief on his Brady claim because, even assuming he could show cause/suppression, he cannot establish prejudice/materiality.
c. Prejudice/Materiality merits analysis
"[P]rejudice within the compass of the 'cause and prejudice' requirement exists when the suppressed evidence is 'material' for Brady purposes." Banks (Dretke ),
Here, even if all the evidence Mr. Simpson claims is material had been disclosed, there is no reasonable probability the jury would have decided on a sentence less than death. See Douglas ,
The only wholly new information withheld was Mr. Collins's prior gang affiliation and the alleged similarities between Mr. Collins's story of his conversation with Mr. Simpson and his prior testimony in the Whitecrow trial. All of the other Collins Evidence related to topics on which evidence was introduced in some form at trial. For example, the State conceded at trial that Mr. Collins wanted to exchange his testimony for favorable treatment, but claimed it never agreed to such a deal. The State also admitted, and the jury was informed, *573that Mr. Collins was a liar, a drug dealer, and a criminal, even if the extent of those lies and crimes was not fully disclosed. In particular, the defense established during trial that Mr. Collins lied on the stand about playing football at the University of Oklahoma. It is true the prosecutor attempted to undermine the effectiveness of this impeachment evidence by suggesting that, in Mr. Collins's "drug-induced mind, he thinks he did [play football at the University of Oklahoma]." Trial Tr. vol. 8 at 19. Nonetheless, the defense efforts at trial made the jury aware that Mr. Collins's recollection of events was questionable at best. The introduction of evidence of additional criminal convictions, or of more factual inaccuracies therefore, would have had diminishing returns.
That said, when considering the suppressed evidence in light of the impeachment evidence introduced at trial, we agree with Mr. Simpson that the suppressed evidence was not all cumulative. See Case v. Hatch ,
As indicated, the State alleged four aggravating factors: 1) the Prior Violent Felony Aggravator, 2) the Risk of Multiple Deaths Aggravator, 3) the HAC Aggravator, and 4) the Continuing Threat Aggravator. Although defense counsel conceded the State had proven beyond a reasonable doubt the first two aggravating factors, counsel argued the State had failed to prove Mr. Palmer's death was especially heinous, atrocious, or cruel or that Mr. Simpson would continue to be a threat in jail. Trial Tr. vol. 8 at 46-47 ("[The prosecutor] told you that he has proven beyond a reasonable doubt all four of the aggravators. I will take issue with him on three and four.... [T]hey didn't prove three and four.").
The State relied on Mr. Collins's testimony to prove Mr. Simpson would be a continuing threat. Id. at 15 ("Now, this is where Roy Collins come[s] in. A continuing threat."); id. at 22 ("[W]e offered Roy Collins for continuing threat."). And Mr. Collins's extensive and inflammatory testimony may have been a factor in the jury's verdict of death. But the question is not whether Mr. Collins was beneficial to the prosecution; the question is whether the prosecutor's case was strong enough that, had the evidence impeaching Mr. Collins been disclosed, there is no reasonable probability the jury would have decided on a sentence less than death. See Douglas ,
Mr. Simpson characterizes Mr. Collins as critical to the State's case in aggravation, claiming, "[Mr.] Collins's testimony that Mr. Simpson tried to hire him to kill [the surviving victim] and assault and threaten witnesses and was utterly remorseless, was the centerpiece of the prosecution's case for death." Aplt. Br. at 53, 77-78. He argues the prosecutor "directed [Mr.] Collins to his theme that [Mr.] Simpson, a high rolling outsider from New Orleans, was a remorseless gangster." Id. at 53. While Mr. Simpson acknowledges there was other evidence to support the Continuing Threat Aggravator, he argues Mr. Collins's testimony was so important that the jury might not have imposed the death penalty without it. To put this argument in context, we must consider the other evidence offered in support of a penalty of death.
*574To begin, Mr. Simpson concedes there was sufficient evidence to support the jury's finding of the first two aggravators: (1) he was convicted previously of a felony involving the use or threat of violence and (2) he knowingly created a great risk of death to more than one person. There is also substantial evidence in the record that supported the Continuing Threat Aggravator, even without considering Mr. Collins's testimony.
First, the facts of the crime itself support this aggravator. See Jones v. State ,
The State also offered other evidence of Mr. Simpson's callous disregard for human life as support for finding the Continuing Threat Aggravator. For example, immediately following the murders, Mr. Simpson proceeded with his plan to visit some women he had met at Fritzi's. The jury could have reasonably inferred a lack of remorse from this conduct and weighed that attitude in favor of finding Mr. Simpson a continuing threat.
Mr. Simpson's attempts to conceal evidence further support a finding that he would be a continuing threat. The record reflects that Mr. Simpson threatened Mr. Dalton's family in an attempt to keep Mr. Dalton from speaking to the police, and that Mr. Simpson's codefendants took his threats seriously.
Mr. Simpson's past criminal convictions can also serve as evidence in support of the Continuing Threat Aggravator. See Lockett v. State ,
Weighing all of the aggravating evidence the State introduced against the previously discussed evidence Mr. Simpson presented in mitigation,16 we find no reasonable probability that the outcome of the sentencing proceeding would have been different had the Collins Evidence been produced. We do not discount the obvious significance of Mr. Collins's testimony or the State's reliance on it. But given the defense's successful, *575if admittedly limited, impeachment of Mr. Collins and the compelling nature of the State's other aggravating evidence, Mr. Simpson "has not convinced us that there is a reasonable probability that the jury would have returned a different verdict if [Mr. Collins's] testimony had been [further] impeached or excluded entirely." See Strickler ,
In summary, because Mr. Simpson cannot establish prejudice, we need not consider whether he could show cause. See McCleskey ,
4. Evidentiary Hearing and Discovery Motions
In conjunction with his Brady claim, Mr. Simpson appeals the district court's denial of his motion for an evidentiary hearing and discovery seeking additional impeachment evidence as to Roy Collins. The district court denied the motion after determining that Mr. Simpson "would not be entitled to relief even if Mr. Collins'[s] testimony was completely discounted or excluded." Simpson IV ,
Generally speaking, federal habeas review "is 'limited to the record that was before the state court that adjudicated the claim on the merits.' " Smith v. Aldridge ,
Here, where the OCCA did not explicitly reach the merits of Mr. Simpson's Brady claim, it is questionable whether § 2254(d)
*576applies to his request for an evidentiary hearing. See
Section 2254(e)(2) of Title 28 states:
If the applicant has failed to develop the factual basis of a claim in State court proceedings, the court shall not hold an evidentiary hearing on the claim unless the applicant shows that-
(A) the claim relies on-
(i) a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable; or
(ii) a factual predicate that could not have been previously discovered through the exercise of due diligence; and
(B) the facts underlying the claim would be sufficient to establish by clear and convincing evidence that but for constitutional error, no reasonable factfinder would have found the applicant guilty of the underlying offense.
Under this provision, "AEDPA ... bars an evidentiary hearing for a nondiligent petitioner unless the petitioner can satisfy both §§ 2254(e)(2)(A) and (B)." Pinholster ,
For the reasons explained above, Mr. Simpson cannot show that the jury would have given him a sentence less than death even with the additional impeachment evidence against Mr. Collins. Accordingly, Mr. Simpson has not satisfied § 2254(e)(2)(B) or the pre-AEDPA standard where § 2254(e)(2) does not apply *577because the petitioner acted diligently in the state court.19 The district court therefore properly denied his motion for discovery and an evidentiary hearing.
C. Consideration of Mitigating Evidence
Mr. Simpson next claims the trial court's instruction and the prosecutor's improper argument unconstitutionally limited the jury's consideration of his mitigating evidence. On direct appeal, the OCCA denied relief, rejecting both prongs of Mr. Simpson's argument. Simpson I ,
We begin our review of this claim with a general overview of the legal background. Next, we examine the OCCA's decision and conclude it adjudicated this issue on the merits. Accordingly, we proceed to the question of whether the OCCA unreasonably applied clearly establish law or unreasonably determined the facts. Under AEDPA's deferential standard of review, we deny relief on this claim.
1. Legal Background
"The Supreme Court has repeatedly held that the Constitution requires that a jury 'cannot be precluded from considering, as a mitigating factor, any aspect of a defendant's character or record ... that the defendant proffers as a basis for a sentence less than death.' " Hanson v. Sherrod ,
*5782. OCCA Decision
On direct appeal, Mr. Simpson argued that the instruction on mitigating evidence, combined with the prosecutor's improper argument, unconstitutionally prevented the jury from considering relevant evidence in mitigation. The OCCA rejected this claim on the merits, stating: "A review of the prosecutor's closing argument concerning the mitigating evidence instruction, the mitigating evidence itself and all instructions concerning mitigation evidence given in this case supports our conclusion that the jurors' consideration of the evidence offered in mitigation was not unfairly limited in this case." Simpson I ,
3. Reasonableness of the OCCA Decision
a. Mitigation instruction
Mr. Simpson first claims the language of Oklahoma's uniform jury instructions improperly precluded the jury from considering evidence that did not "extenuate or reduce the degree of [his] moral culpability or blame." Aplt. Br. at 80-81. We rejected this exact challenge in Hanson , and we must do so again today.
In Hanson , this court considered the constitutionality of the same instruction used in Mr. Simpson's case: "Mitigating circumstances are those which, in fairness, sympathy, and mercy, may extenuate or reduce the degree of moral culpability or blame. The determination of what circumstances are mitigating is for you to resolve under the facts and circumstances of this case."
b. Prosecutor's closing argument
More compelling is Mr. Simpson's assertion that the prosecutor made improper comments designed to mislead the jurors into believing they could not legally consider Mr. Simpson's mitigating evidence unless it reduced his moral culpability or blame. Throughout his closing argument, the prosecutor made no less than nine separate statements which either generally defined mitigating evidence as reducing moral culpability or blame or specifically compared Mr. Simpson's mitigating factors to that definition ("Moral Culpability Comments").21 One example of *579this came near the end of closing argument as the prosecutor was summarizing Mr. Simpson's mitigating evidence:
There is not one bit of mitigating evidence that reduces [Mr. Simpson's] degree of moral culpability. That's what the law is. Does [the] mitigating circumstance reduce his degree of moral culpability or blame?
Look at [the instruction]. Not one bit. Not his age, not his family, certainly not them. They're good people. They don't want to be here. He brought them into it, too.
And his mental condition, there's nothing wrong with him. There's not one bit of evidence that reduces his degree of moral culpability or blame. And [Dr. Massad] didn't tell you that, even if for some reason the P.h.D. [sic] convinces you, okay, he's got Post-Traumatic Stress, how does that reduce his degree of blame?
Trial Tr. vol. 8 at 31 (emphasis added). The record is replete with similar Moral Culpability Comments.22 But we are constrained by AEDPA's deferential standard from providing relief to Mr. Simpson on this basis.
Several cases guide our analysis of this issue. In Boyde , the Supreme Court held a prosecutor's statements, that "the mitigating evidence did not 'suggest that petitioner's crime is less serious or that the gravity of the crime is any less' and that 'nothing I have heard lessens the seriousness of this crime,' " were not improper attempts to narrow the jury's consideration of mitigating evidence.
Although these decisions are informative, Mr. Simpson's case has some key distinctions. The prosecutor began his discussion of Mr. Simpson's mitigating evidence by advancing an improperly narrow definition of mitigating evidence23 as "what the law is." Trial Tr. vol. 8 at 31. He *580then systematically and repeatedly attacked Mr. Simpson's age,24 mental state,25 and family support,26 both individually and collectively,27 as failing to meet that definition. While a prosecutor may "comment[ ] on the weight that should be accorded to the mitigating factors," he cannot preclude the jury from "giving effect to the mitigating evidence" or "suggest that the jury was not permitted to consider the factors." Fox v. Ward ,
Mr. Simpson's case is closer to our recent decision in Grant . As in Mr. Simpson's case, an Oklahoma jury convicted Mr. Grant of murder and then sentenced him to death. See Grant ,
In rebuttal, the prosecutor emphasized the limiting language of the mitigating instruction *581by telling the jury, "the law tells you what [the definition of mitigating circumstances] means.... It says that mitigating circumstances are those which reduce the moral culpability or blame of the defendant. That those things, in order to be mitigating, must reduce his moral culpability or blame."
Mr. Grant appealed to the OCCA, arguing "that the prosecutor focused on only one part of the definition of mitigating evidence, and thus unfairly limited the jurors' consideration of the evidence he had offered as mitigating."
Despite the pervasive nature of the prosecutor's Moral Culpability Comments in Mr. Simpson's case, the OCCA concluded the jury's consideration of the evidence was "not unfairly limited" by "the prosecutor's closing argument concerning the mitigating evidence instruction, the mitigating evidence itself and all instructions concerning mitigating evidence." Simpson I ,
But the comments do not stand alone. The jury received constitutionally sound jury instructions-including one specifically identifying the categories of evidence offered in mitigation-and Mr. Simpson offered extensive evidence on each of those topics. See Section I.B.1.a.ii, supra . Under these circumstances, we cannot *582say that no fairminded jurist would agree with the OCCA's conclusion that the jury was not precluded from considering the evidence offered by Mr. Simpson in mitigation. See Richter ,
D. Prosecutorial Misconduct
Mr. Simpson claims that, during the closing arguments in his sentencing trial, the prosecutor made improper comments that rendered his trial so fundamentally unfair it deprived him of his due process rights. The OCCA denied this claim on direct appeal, holding that any improper comments did not render Mr. Simpson's sentencing trial fundamentally unfair when considered within the context of the entire trial. Simpson I ,
We begin our review of this claim by first setting forth the OCCA's decision. We next consider the proper standard of review, rejecting Mr. Simpson's claim that the OCCA's decision is so unclear as to be unentitled to AEDPA deference. Having concluded the claim is subject to AEDPA deference, we then provide a discussion of the general legal background governing claims of prosecutorial misconduct affecting the fundamental fairness of a proceeding. Ultimately, we conclude the OCCA's decision is not unreasonable under AEDPA's deferential standard, and we deny relief on this claim.
1. OCCA Decision
Mr. Simpson raised his prosecutorial misconduct claim on direct appeal. Reviewing for plain error, the OCCA denied relief, stating:
The alleged instances of [prosecutorial] misconduct include allegations that the prosecutor argued facts not in evidence, engaged in unnecessary ridicule of [Mr. Simpson], contrasted [Mr. Simpson's] situation with that of the victims', appealed to justice and sympathy for the victims and their families and improperly shifted the burden of proof. Many of these comments, including the single comment met with objection, fell within the broad parameters of effective advocacy and do not constitute error. We review those comments bordering upon impropriety within the context of the entire trial, considering not only the propriety of the prosecutor's actions, but also the strength of the evidence against the defendant and the corresponding arguments of defense counsel. Given the magnitude of the State's evidence against [Mr. Simpson,] this Court finds that any inappropriate comments not objected *583to did not deprive [Mr. Simpson] of a fair trial or affect the jury's finding of guilt or assessment of punishment. There was no plain error here.
2. Standard of Review
Mr. Simpson claims this court should review his prosecutorial misconduct claims de novo for two reasons. First, he argues the OCCA did not adjudicate his federal claim on the merits. Second, Mr. Simpson contends that, even if the OCCA intended to resolve some of his prosecutorial misconduct claims on the merits, its decision is not entitled to AEDPA deference because it is unclear which claims the OCCA adjudicated on the merits and which it did not. We address each argument in turn.
a. Adjudication on the merits
"[W]hen a federal claim has been presented to a state court and the state court has denied relief, it may be presumed that the state court adjudicated the claim on the merits in the absence of any indication or state-law procedural principles to the contrary." Johnson v. Williams ,
Mr. Simpson attempts to make this showing by pointing to the OCCA's statement that it "will not grant relief based on prosecutorial misconduct unless the State's argument is so flagrant and that it so infected the defendant's trial that it was rendered fundamentally unfair." Simpson I ,
For these reasons, we review Mr. Simpson's claim under AEDPA, and he is entitled to relief only if the OCCA's decision was an unreasonable application of clearly established federal law.29
*584b. Scope of decision on the merits
The OCCA noted that it had reviewed the alleged misconduct and found that "[m]any of these comments ... fell within the broad parameters of effective advocacy and do not constitute error."
In Douglas ,
3. Legal Background
A prosecutor's misconduct will warrant a new trial only where the improper statements "so infected the trial with unfairness as to make the resulting conviction a denial of due process." Le v. Mullin ,
*585"Ultimately, this court considers the jury's ability to judge the evidence fairly in light of the prosecutor's conduct."
Given the nature of prosecutorial misconduct claims, we evaluate the prejudicial impact of any improper comments individually and collectively. See id. at 1022 ("Our cases on prosecutorial misconduct make it clear that we must consider all the complained of conduct in toto because individual, harmless prosecutorial errors can add up to make a trial fundamentally unfair in the aggregate."). "In death-penalty cases, we review whether the improper comments as a whole so infected the trial with unfairness as to ... render[ ] the sentencing fundamentally unfair in light of the heightened degree of reliability demanded in a capital case." Bland ,
4. Merits
Mr. Simpson claims the prosecutor made improper comments during closing argument that fall into four broad categories: (1) Moral Culpability Comments; (2) denigration of mitigation evidence; (3) improper comparison between the victims and the defendant; and (4) improper calls for the death penalty as a civic responsibility. Mr. Simpson did not raise contemporaneous objections to these comments. As a result, the OCCA reviewed for plain error. Simpson I ,
a. Moral Culpability Comments
Having already identified the Moral Culpability Comments challenged by Mr. Simpson, we turn to the propriety of such comments and whether any of them, individually or cumulatively, denied Mr. Simpson a fundamentally fair sentencing trial. Here, we are guided by our decision in Le . In Le , the prosecution made the following statements during closing arguments regarding the defendant's mitigating evidence:
We have a whole list of things that have been submitted as mitigating circumstances. The Court instructs you that mitigating circumstances are those which in fairness and mercy-get this-may be considered as extenuating or reducing the moral culpability or blame. It doesn't say anything about whether you've been a good guy in the past or anything like that. Do these circumstances extenuate or reduce the degree of moral culpability o[r] responsibility for what he did? It's up to you to decide what are mitigating circumstances.
The defense talks about Mr. Le being a hard worker, a machinist, invent[or], a good teacher, teaching English to Vietnamese people, good to family. Does that in any way officiate (sic) or mitigate or relieve or make any less horrible what he did to [the victims]? I submit to you they do not. He's good to his family. He's got five things on here about his family. Well, nearly everybody is good to their family. Does it make it all right to go out and murder? Does it make you less guilty when you go out and commit this kind of a crime?
Like in Mr. Simpson's case, the prosecutor construed the instruction as limited to evidence that reduces moral culpability or *586blame and then specifically argued Mr. Le's evidence did not meet that criteria. In Le, we determined the prosecutor's remarks were irrelevant, improper, and "may have implied that the jury had the ability to ignore the legal requirement that it must consider mitigating evidence."
Here, we are compelled to reach the same result. The Moral Culpability Comments were improper and pervasive. Nevertheless, the evidence of Mr. Simpson's guilt was overwhelming, the State presented powerful aggravating evidence, and we have already concluded the jury was not precluded from considering Mr. Simpson's mitigating evidence. As we now explain, when we view the misconduct in the context of the entire proceeding, we cannot conclude the OCCA acted unreasonably in holding that the prejudicial impact of these comments, individually or cumulatively, did not render the sentencing trial fundamentally unfair.
b. Denigration of mitigation evidence
Mr. Simpson asserts several instances where he claims the prosecutor improperly denigrated his mitigating evidence. Prosecutors are given a "wide latitude of argument," Thornburg v. Mullin ,
Mr. Simpson challenges five statements30 in which he alleges the prosecutor shamed him for relying on his family support31 and his mental condition32 as mitigating *587factors. For example, the prosecutor called Mr. Simpson's PTSD diagnosis an "excuse"33 and an "insult"34 to "legitimate people with PTSD."35 It is appropriate for the prosecutor to argue based on the record facts that Mr. Simpson did not actually suffer from PTSD and was instead using it as an excuse to avoid responsibility. But characterizing Mr. Simpson's diagnosis as an "insult to all legitimate people with PTSD" and "legitimate veterans" strays into inappropriate personal opinion. Similarly, the prosecutor's comments suggesting the defense should be ashamed for relying on Mr. Simpson's family support and mental health improperly denigrated Mr. Simpson's mitigating evidence. See Cuesta-Rodriguez v. Royal , No. CIV-11-1142-M,
Although several of these statements were improper, none of them, separately or cumulatively, rises to the level necessary to have deprived Mr. Simpson of a fundamentally fair sentencing proceeding. Similar improper prosecutorial statements have rarely been held, standing alone, to render a trial fundamentally unfair. This is especially so in a case, such as this one, where the State has presented significant evidence in aggravation. See generally Le ,
c. Improper comparison with the victims
Mr. Simpson next objects to the prosecutor's statement: "Of course, [Mr. Simpson's family would] go to the penitentiary to see him. Of course they would. You know, they're good people. These victims can't. They can go to the cemetery." Trial Tr. vol. 8 at 25. We agree that "it is prosecutorial misconduct for the prosecution to compare the plight of the victim with the life of the defendant in prison." Bland ,
d. Justice demands a death sentence
We have also held that "it is improper for a prosecutor to suggest that a jury has a civic duty to convict." Bland ,
Justice in this case demands you to do the most difficult thing you have to do in fulfilling your civic duty as a juror . Justice for Glen Palmer, for his family, justice for Anthony Jones and his family, demands that you render a verdict of the death penalty in this case. Justice demands it. And it will be difficult but, ladies and gentlemen, I'm going to ask you to let your verdict speak to this Defendant. Let your verdict speak to Glen Palmer's family. Let your verdict speak to Anthony Jones'[s] family.
Let your verdict speak to the carnage that this Defendant has left behind and his commitment to be a criminal and a cold-blooded killer. And let your verdict speak for the community that in this kind of a case for this Defendant there is one just verdict and only one and that is to recommend a sentence of death .
Trial Tr. vol. 8 at 63-64 (emphasis added).
Despite the impropriety of the prosecutor's argument, we are not convinced this comment, on its own, deprived Mr. Simpson of a fundamentally fair sentencing proceeding in view of the "overwhelming evidence of Mr. [Simpson's] guilt, evidence of aggravating factors supporting the death sentence, [and] the general content of the instructions to the jury." See Le ,
e. Totality of prosecutorial misconduct
Although we have identified a substantial number of improper prosecutorial statements, none of them, standing alone, was sufficiently prejudicial to deny Mr. Simpson his due process rights. "[B]ecause individual, harmless prosecutorial errors can add up to make a trial fundamentally unfair in the aggregate,"
Given the extensive and recurring misconduct committed by the prosecutor, it is appropriate to question whether the jury was able to judge the evidence fairly. But the OCCA answered that question affirmatively and, under AEDPA, we are bound by the OCCA's "ruling unless it constitutes an unreasonable application of the cumulative-error doctrine." See Thornburg ,
E. Especially Heinous, Atrocious, or Cruel Aggravator
Mr. Simpson next claims there is insufficient evidence to support the jury's finding that the murder of Glen Palmer was heinous, atrocious, or cruel and that the HAC Aggravator is unconstitutionally overbroad.
*589In addressing this claim, we begin by discussing the general legal background governing challenges to capital aggravators. Next, we provide additional factual and procedural background, including the resolution of Mr. Simpson's claim in the state court proceedings and in the district court. Although Mr. Simpson raised both a sufficiency-of-the-evidence claim under the Fourteenth Amendment and a vagueness claim under the Eighth Amendment in the state court,36 we determine that he abandoned his Eighth Amendment argument in the district court. We therefore consider only his Fourteenth Amendment sufficiency-of-the-evidence claim in this opinion. In doing so, we first provide a discussion of the relevant law and then conclude the OCCA's decision holding that the evidence is sufficient to support the HAC aggravator as to Mr. Palmer is not unreasonable. As a result, we deny relief on this claim.
1. Legal Background
As we recently explained in Wood v. Carpenter , a defendant can challenge the jury's finding of a capital aggravator in two ways:
First, a defendant can bring a sufficiency of the evidence claim under Jackson v. Virginia ,443 U.S. 307 , 316 [99 S.Ct. 2781 ,61 L.Ed.2d 560 ] (1979). It violates the Fourteenth Amendment's guarantee of due process if a jury sentences a defendant to death based on an aggravator, even though there was insufficient evidence for any rational juror to have concluded the aggravator was met. Because state law defines aggravators, this question turns on state law.
Second, petitioners can challenge an aggravating circumstance as unconstitutionally vague. It violates the Eighth and Fourteenth Amendments for death sentences to be arbitrarily imposed. As a consequence, if an aggravating circumstance is so vague it could apply to any and every murder, then sentencing a defendant to death because that aggravator was met violates the Constitution.
The distinction between these two methods of challenging a capital aggravator is important here because although Mr. Simpson initially pursued both avenues, he later abandoned his Eighth Amendment claim. We now discuss the evolution of Mr. Simpson's claims regarding the HAC Aggravator.
2. Factual and Procedural Background
a. Trial
During the sentencing stage of Mr. Simpson's trial, the jury was instructed that, to impose the HAC Aggravator, it must find the State had proven beyond a reasonable doubt that the murder of Mr. Palmer "was preceded by either torture of the victim or serious physical abuse of the victim." Trial R. vol. 3 at 600. The trial court further instructed that torture is defined as "the infliction of either great physical anguish or extreme mental cruelty."
In his closing statement, the prosecutor told the jury the State "must prove ... that the murder in this case of Glen Palmer was either preceded by torture or serious *590physical abuse." Trial Tr. vol. 8 at 10. The prosecutor then conceded, "[t]here's no question it's not torture," but he asserted that it did constitute "serious physical abuse."
b. OCCA and district court decisions
On direct appeal, Mr. Simpson claimed there was insufficient evidence to support the HAC Aggravator under the Fourteenth Amendment and that to apply it to the facts of this case would broaden the aggravator beyond the constitutional limits proscribed by the Supreme Court and the Eighth Amendment. The OCCA did not address Mr. Simpson's Eighth Amendment claim, but held there was sufficient evidence to support the HAC Aggravator for Mr. Palmer:
With regard to the murder of Glen Palmer, the evidence showed that Palmer was shot four times. He suffered a grazing gunshot wound to the right shoulder, two superficial gunshot wounds to the left side of his back, and an ultimately fatal gunshot wound to his chest. Although he was initially conscious after being shot, his breathing became labored and he made gurgling sounds as his chest filled with blood before he died. There was testimony that immediately after he had been shot, Palmer was able to speak, was aware that he had been shot and was fearful that the shooters would return. Reviewing the evidence in the light most favorable to the State, we find that the evidence supports a finding that Palmer's death was preceded by physical suffering and mental cruelty.
Simpson I ,
In the district court, Mr. Simpson renewed his claim that there was insufficient evidence to support the HAC Aggravator as to Mr. Palmer, but he did not argue the HAC Aggravator was unconstitutionally vague, either on its face or as applied to him. The district court held the OCCA's decision was not unreasonable "in light of the double deference afforded it" when reviewing sufficiency of the evidence claims under AEDPA. Simpson IV ,
3. Preservation
The State argues we should review only Mr. Simpson's Fourteenth Amendment sufficiency-of-the-evidence challenge because Mr. Simpson did not preserve the Eighth Amendment vagueness claim by failing to raise it in the district court and by inadequately briefing it in his opening brief to this court. Mr. Simpson asserts that he has "always argued the Fourteenth Amendment insufficiency-of-the-evidence claim cannot be assessed in a vacuum, and that [the] OCCA must assess the evidence under a constitutionally *591narrow standard." Aplt. Reply Br. at 33. In support, he points to a single footnote in his opening brief to the district court which merely requested supplemental briefing on the HAC Aggravator because the page constraints on his brief did "not permit a complete analysis of ... the unreasonable failure of the OCCA to abide by the limiting requirements of the Supreme Court in Maynard v. Cartwright ,
By not raising an Eighth Amendment challenge to the HAC Aggravator in the district court and inadequately briefing it here, Mr. Simpson has failed to preserve that claim.37 See Stouffer v. Trammell ,
4. Sufficiency of the Evidence
a. Additional legal background
We review the sufficiency of the evidence "under the 'rational fact-finder' standard announced in Jackson v. Virginia,
Under Oklahoma law, to establish the HAC Aggravator, the State must prove beyond a reasonable doubt "that the murder of the victim was preceded by torture *592or serious physical abuse, which may include the infliction of either great physical anguish or extreme mental cruelty." Warner v. State ,
b. Merits
As discussed, because the OCCA decided Mr. Simpson's sufficiency-of-the-evidence claim on direct appeal, AEDPA constrains our review. Review of sufficiency of the evidence under AEDPA "adds an additional degree of deference, and the question becomes whether the OCCA's conclusion that the evidence was sufficient constituted an unreasonable application of the Jackson standard." Hooks II ,
Here, the State relied on the testimony of Dr. Jeffrey Grofton, the coroner who performed Mr. Palmer's autopsy, and London Johnson, the surviving victim, to establish that Mr. Palmer experienced conscious physical suffering. Mr. Palmer was shot four times, but was conscious long enough to perceive that he had been shot and to fear further injury. Mr. Johnson, who was in the car with Mr. Palmer and Mr. Jones when it was suddenly fired upon, testified that when he opened the car door, Mr. Palmer told him to "[s]hut that door. They're going to come back." Trial Tr. vol. 3 at 42. Mr. Palmer then revealed he had been shot and was unable to move. Mr. Johnson also testified that Mr. Palmer's breathing "sounded like he was-like he was trying to breathe, but he had blood in his throat." Trial Tr. vol. 3 at 45. Dr. Grofton testified that Mr. Palmer possibly experienced difficulty breathing because "the left side of [his] chest was filling up with blood which would essentially collapse the left lung making it exceedingly difficult to breathe." Trial Tr. vol. 5 at 162-63. Mr. Palmer died before emergency assistance arrived.
Although Mr. Palmer did not expressly state he was in pain, and neither Dr. Grofton nor Mr. Johnson testified as to how long Mr. Palmer was conscious or whether he appeared to be in pain, the jury could have reasonably inferred that Mr. Palmer experienced conscious physical suffering based on the evidence about his wounds. Mr. Palmer was conscious and able to speak for some period of time before he died. He was aware of his injuries and struggled to breathe as his lungs filled with blood. Viewing the evidence in the light most favorable to the State and applying AEDPA's deferential standard of *593review, we cannot conclude the OCCA acted unreasonably in deciding there was sufficient evidence to support the jury's finding that Mr. Palmer experienced conscious physical suffering as defined by Oklahoma law. We therefore deny Mr. Simpson relief on this claim.
F. Ineffective Assistance of Counsel
Mr. Simpson alleges his trial counsel was ineffective during both the guilt and sentencing stages of the trial. With respect to the guilt stage, Mr. Simpson contends trial counsel was ineffective for failing to request a second-degree murder instruction. As to the sentencing stage of trial, Mr. Simpson argues trial counsel preformed ineffectively by failing to: (1) investigate, prepare, and present lay witnesses, (2) object to improper prosecutorial arguments, (3) object to the mitigating evidence jury instruction, and (4) object to the HAC jury instruction.
In reviewing this claim, we begin with a general discussion of the relevant legal background. We then consider each allegation of ineffective performance individually. In doing so, we provide any further discussion of law pertinent to the particular allegation of ineffectiveness. We then review the OCCA's decision to determine whether it rejected that claim on the merits. Finally, we address whether the OCCA's merits decision was reasonable. In each instance, we conclude the OCCA's merits decision was not contrary to or an unreasonable application of Supreme Court law and was not based on an unreasonable determination of the facts. See
1. Legal Background
Claims of ineffective assistance of counsel are evaluated under the two-prong approach established by the Supreme Court in Strickland v. Washington ,
Even if counsel performed in a constitutionally deficient manner, Mr. Simpson is not entitled to relief unless he can prove actual prejudice. See Strickland ,
Review under both AEDPA and Strickland is "highly deferential, and when the two apply in tandem, review is 'doubly' so." Richter ,
2. Failure to Investigate, Prepare, and Present Lay Witnesses
a. Additional legal background
Under Strickland , "counsel has a duty to make reasonable investigations or to make a reasonable decision that makes particular investigations unnecessary."
b. OCCA decision
Mr. Simpson argued that trial counsel rendered constitutionally ineffective assistance relative to the investigation and presentation of mitigating evidence at the sentencing stage. On direct appeal, the OCCA stated:
Next, [Mr. Simpson] complains that defense counsel was ineffective for failing to adequately investigate and present additional evidence of innocence. He first specifically complains that counsel was ineffective for failing to investigate and present additional mitigating evidence. While [Mr. Simpson] has shown this Court that additional mitigation witnesses could have been called and others that were called could have given additional testimony, he has not shown a reasonable probability that but for counsel's alleged unprofessional error in not presenting this evidence, the result of the proceeding would have been different.
Simpson I,
*595c. Merits
Mr. Simpson faults his trial counsel for not presenting a more comprehensive picture of his troubled upbringing. On direct appeal, evidence surfaced that Mr. Simpson's mother became addicted to crack cocaine when he was a young child and that drug use and violence were common in the home. In the midst of this instability, Mr. Simpson became sexually active at fourteen and had fathered children with two separate women by the time he was sixteen years old. He also began skipping school, using and selling drugs, committing burglaries, and carrying guns as early as age fourteen. The evidence on direct appeal further indicated that Mr. Simpson reported being sexually assaulted as a teenager. Mr. Simpson faults his trial counsel for failing to develop the story of his traumatic childhood.
To properly analyze Mr. Simpson's claim, we first look at the evidence presented in mitigation during sentencing. Recall that the defense relied heavily on Dr. Massad's testimony and the testimony of Mr. Simpson's family about the paranoia Mr. Simpson exhibited after he was shot. From this evidence, the jury was informed of the violence surrounding Mr. Simpson during his teenage years; for what evidence could be more indicative of a violence-filled upbringing than Mr. Simpson being comatose for two months as a result of sustaining five gunshot wounds in a drive-by shooting. And the shooting of Mr. Simpson occurred in retaliation for him deciding not to kill a witness slated to testify against one of his friends-a friend who had been involved in a violent crime. Thus, one of the thrusts of the evidence Mr. Simpson proffers in support of this ineffective assistance of counsel claim was, to some degree, already before the jury such that its theoretical mitigating value is minimized. Cf. Grant ,
The mitigating value of the unpresented evidence is further decreased when considered in light of the prosecution's potential response. If the State had an opportunity to respond to Mr. Simpson's additional mitigating evidence, it is not apparent the jury would have viewed the evidence about Mr. Simpson's upbringing, on the whole, as mitigating. Rather, a reasonable jurist could conclude the evidence would have actually increased the odds of a verdict of death as, by Mr. Simpson's own admission, he, before turning sixteen, had already (1) dropped out of school; (2) impregnated two different women; (3) sold drugs; (4) committed burglaries; and (5) routinely carried a firearm. New and additional evidence from the State on these matters would have reduced any sympathy the jury had for Mr. Simpson because the evidence would not only have painted Mr. Simpson as living a lawless life contrary to the norms and expectations of society, but also would have furthered the State's argument relative to the continuing threat aggravator.
Apart from the potential response by the state to the additional mitigating evidence, we cannot conclude the OCCA reached an unreasonable conclusion on the prejudice prong of Strickland when all the mitigating evidence is considered in light of the aggravating evidence. The state presented strong evidence in support of the death sentence, and the additional mitigation does little, if anything, to undermine *596the aggravating factors found by the jury. A key aspect of Mr. Simpson's offense and a key aspect of his history and characteristics highlight the reasonableness of the OCCA's conclusion. First, in committing his offense, Mr. Simpson sprayed fifteen to twenty bullets at the moving car driven by Mr. Palmer while the vehicle was passing through a residential area. Thus, not only did Mr. Simpson's conduct result in the deaths and serious wounding of the three individuals in the vehicle, it also endangered the lives of other uninvolved persons. Second, and of significant persuasive value, the State presented compelling testimony from Mr. Pham, whom Mr. Simpson had shot in the back of the head, execution-style, after forcing his way into Mr. Pham's house and stealing Mr. Pham's wallet.
In light of the strong evidence offered by the State, as well as the State's likely response to the additional mitigation evidence Mr. Simpson's trial counsel did not present, we conclude Mr. Simpson has not demonstrated the OCCA unreasonably applied Strickland and its progeny when it concluded Mr. Simpson was not prejudiced by any alleged deficient performance by counsel. We therefore deny relief on this claim.38
3. Failure to Preserve the Record
Mr. Simpson next raises ineffective assistance of counsel claims based on several instances where trial counsel allegedly failed to preserve issues for appeal. We address Mr. Simpson's claim that counsel was ineffective for failing to request a second-degree murder instruction, before we turn to the alleged failures we have already rejected as stand-alone claims for habeas relief.
a. Failure to request a jury instruction on second-degree murder
Mr. Simpson first asserts that trial counsel was constitutionally ineffective for failing to request an instruction on second-degree depraved mind murder. For the reasons we now explain, we deny relief on this claim.
i. Additional legal background
For counsel's failure to request a lesser-included offense instruction to constitute deficient performance, Mr. Simpson must have been entitled to such an instruction based on the evidence presented at trial. See Bland ,
*597Hooker v. State ,
ii. OCCA decision
In Mr. Simpson's case, the OCCA analyzed two claims related to the Second Degree Depraved Mind Murder instruction. The OCCA first determined Mr. Simpson was not entitled to the instruction on the merits:
[Mr. Simpson] argues that an instruction on th[e] lesser offense [of Second Degree Depraved Mind Murder] was warranted because at most, the evidence showed that he simply fired into the car in which [Mr.] Palmer, [Mr.] Jones and [Mr.] Johnson were riding. He asserts ... there was no evidence that he intended to kill his victims.... We find otherwise. In light of the testimony that [Mr. Simpson] threatened to "chop" up [Mr.] Palmer and his companions, instructed [Mr.] Dalton to follow [Mr.] Palmer's car and then shot as many as twenty rounds at the moving vehicle with an assault rifle, we find that the evidence did not reasonably support the conclusion that [Mr. Simpson] did not intend to kill the men in the Chevy. An instruction on Second Degree Depraved Mind Murder was not warranted by the evidence....
Simpson I ,
The OCCA then considered whether Mr. Simpson's counsel was ineffective for failing to request the second-degree murder instruction. The court stated, in relevant part:
[Mr. Simpson] first argues that trial counsel was ineffective for failing to object to ... the submission of improper jury instructions and verdict forms. These alleged failings concern issues raised and addressed above.... We found in Proposition III that an instruction on Second Degree Depraved Mind Murder was not warranted by the evidence.... Most of these alleged failings do not reflect a deficient performance by defense counsel and [Mr. Simpson] has not shown a reasonable probability that, but for counsel's alleged unprofessional errors, the result of the proceeding would have been different.
Mr. Simpson relies on the OCCA's statement that, "[m]ost of these alleged failings do not reflect a deficient performance by defense counsel." Simpson I ,
The OCCA's analysis addressed eight alleged failings of counsel, some of which (the admission of hearsay evidence and the failure to object to the HAC Aggravator for Mr. Jones) the court specifically found were error.
iii. Merits
Mr. Simpson argues the jury should have been instructed on second-degree depraved mind murder because there was "ample evidence putting the issue of specific intent in question."39 Aplt. Br. at 45. Again, we disagree.
As the OCCA noted, Mr. Simpson "threatened to 'chop up' [Mr.] Palmer and his companions," Simpson I ,
Trial counsel was not required to request an instruction that was not reasonably supported by the evidence. See Grissom v. Carpenter ,
b. Failure to object to improper prosecutorial arguments
Next, Mr. Simpson contends his counsel performed deficiently by failing to object to improper prosecutorial arguments.
i. OCCA decision
The OCCA considered this claim together with the ineffective assistance of counsel claim discussed above and stated, in relevant part:
In Proposition VI, we found that none of the alleged improper comments made by the prosecutor could be found to have affected the jury's finding of guilt or assessment of punishment.... Most of these alleged failings do not reflect a deficient performance by defense counsel and [Mr. Simpson] has not shown a reasonable probability that, but for counsel's alleged unprofessional errors, the result of the proceeding would have been different.
Simpson I ,
ii. Merits
We held in Section III.D, supra , that nearly all of the prosecutorial arguments Mr. Simpson challenges-the Moral Culpability Comments and comments denigrating the evidence in mitigation, comparing the victims' deaths to Mr. Simpson's incarceration, and calling for the death penalty as a civic duty-were improper. Trial counsel made a motion in limine to prohibit prosecutorial argument of this nature, but made no further objection to these improper comments during the sentencing trial. Failing to do so "fell below an objective standard of reasonableness,"see Strickland ,
c. Failure to object to the "mitigation evidence" jury instruction
As his next basis for ineffective assistance of counsel related to the failure to preserve the record, Mr. Simpson argues his counsel performed deficiently by failing to object to the jury instruction on mitigation evidence. We again disagree.
i. OCCA decision
Mr. Simpson raised this claim on direct appeal. The OCCA addressed Mr. Simpson's challenge to the mitigation instruction in its discussion of the constitutionality of the instruction and briefly in its ineffective assistance of counsel analysis.
*600With respect to the constitutionality of the instruction, the OCCA stated:
In his twelfth proposition, [Mr. Simpson] argues that the definition of mitigating circumstances given to the jury in this case was unconstitutional as it impermissibly limited the jury's consideration of mitigating evidence. This Court has consistently upheld constitutional challenges to the instruction at issue.
Simpson I ,
The OCCA also rejected Mr. Simpson's ineffective assistance of counsel claim based on trial counsel's failure to object to that instruction:
In his thirteenth proposition, [Mr. Simpson] argues that he was denied his Sixth Amendment right to the effective assistance of counsel for several alleged failings of trial counsel.... In support of his proposition, [Mr. Simpson] first argues that trial counsel was ineffective for failing to object to ... the submission of improper jury instructions and verdict forms. These alleged failings concern issues raised and addressed above.... In Proposition XII, we found that the jurors' consideration of the evidence offered in mitigation in this case was not unfairly limited. Most of these alleged failings do not reflect a deficient performance by defense counsel and [Mr. Simpson] has not shown a reasonable probability that, but for counsel's alleged unprofessional errors, the result of the proceeding would have been different.
Id . at 904.
From this discussion, it is fair to conclude the OCCA found no deficient performance with respect to trial counsel's failure to object to the mitigation instruction. First, the OCCA held the instruction was constitutionally sound, noting it had been repeatedly upheld in the face of challenges.
ii. Merits
In Section III.C, supra , we evaluated the merits of Mr. Simpson's challenge to the jury instruction on mitigating evidence and concluded the OCCA acted reasonably in denying relief because the instruction correctly stated the law. Although we concluded that counsel's failure to object to the prosecutor's misuse of the instruction constituted deficient performance, counsel is not expected to object to legally accurate jury instructions. See Castro ,
d. Failure to object to the HAC jury instruction
Finally, Mr. Simpson argues his counsel was ineffective for failing to object to the HAC jury instruction because the instruction "failed to clarify the HAC [A]ggravator was not to be alleged for Anthony Jones." Aplt. Br. at 48. Recall that, although the State did not assert the HAC Aggravator with respect to the murder of Mr. Jones, the jury found it had been proved beyond a reasonable doubt as to the murder of Mr. Palmer and as to the murder of Mr. Jones. Mr. Simpson claims trial counsel could have avoided this confusion by objecting to the instruction for the murder of Mr. Jones, which erroneously listed the HAC Aggravator as an option that could be found unanimously by the jury.40
i. OCCA decision
On direct appeal, the OCCA rejected Mr. Simpson's ineffective assistance of counsel claim based on the HAC instruction. In considering Mr. Simpson's standalone, non-ineffective-assistance-of-counsel challenge to the HAC Aggravator as to Mr. Jones's death, the OCCA concluded the challenge was "well taken" and struck the aggravator. Simpson I ,
When the OCCA reached Mr. Simpson's ineffective assistance of counsel claim relative to the jury instruction on the HAC Aggravator, it stated:
[W]e found that the heinous, atrocious or cruel aggravating circumstance was proven beyond a reasonable doubt as to the murder of Glen Palmer. Although this aggravating circumstance was stricken as to the murder of Anthony Jones, [Mr. Simpson's] jury did not consider improper aggravating evidence in deciding punishment.... Most of these alleged failings do not reflect a deficient performance by defense counsel and [Mr. Simpson] has not shown a reasonable probability that, but for counsel's alleged unprofessional errors, the result of the proceeding would have been different.
ii. Merits
Because the OCCA rejected Mr. Simpson's ineffective assistance of counsel claim on the merits, we afford its decision deference under § 2254(d). We conclude the OCCA did not act unreasonably in rejecting Mr. Simpson's claim. We have already determined that the instruction was a correct statement of Oklahoma law, and the OCCA struck the aggravator as to Mr. Jones. Because there was no evidence introduced solely to support the HAC Aggravator, we cannot conclude that the OCCA's decision that Mr. Simpson was not prejudiced was unreasonable. Accordingly, we deny Mr. Simpson relief on this claim.
G. Cumulative Error
Mr. Simpson's final claim is that even if the individual errors in his trial do not warrant relief, their cumulative impact denied him a fundamentally fair trial and sentencing proceeding. We address this claim in three sections. First, we discuss the relevant legal background. Next, we review the OCCA's decision, taking note of the errors it included in its analysis. Finally, having found no errors the OCCA did not include in its analysis, we review the reasonableness of its decision under AEDPA's deferential standard of review. Ultimately, we conclude the OCCA's decision was reasonable, and we deny Mr. Simpson relief on this claim.
1. Legal Background
"Cumulative error analysis is an extension of harmless error and conducts the same inquiry as for individual error, focusing on the underlying fairness of the trial." Darks ,
2. OCCA Decision
On direct appeal, the OCCA denied Mr. Simpson relief on his cumulative error claim, concluding that, "[a]ny errors were harmless beyond a reasonable doubt, individually *603and cumulatively." Simpson I ,
3. Merits
Upon reviewing Mr. Simpson's claims, we, like the OCCA, have identified four sentencing-stage errors that do not individually entitle Mr. Simpson to habeas relief: (1) prosecutorial misconduct; (2) counsel's deficient performance in failing to investigate and present further mitigating evidence regarding Mr. Simpson's upbringing;41 (3) counsel's deficient performance in failing to object to the prosecutorial misconduct; and (4) counsel's deficient performance in failing to object the HAC Aggravator jury instruction.42
We now determine their cumulative impact. See Cargle v. Mullin ,
*604All the identified errors occurred at the sentencing stage of the trial; therefore, we review whether the errors "rendered the sentencing fundamentally unfair in light of the heightened degree of reliability demanded in a capital case." Thornburg ,
The OCCA held the cumulative effect of these errors was "harmless beyond a reasonable doubt." See Simpson I ,
Under these circumstances, the OCCA's cumulative error analysis is not unreasonable, and Mr. Simpson is not entitled to habeas relief as to his death sentences.43
IV. CONCLUSION
We AFFIRM the district court's denial of federal habeas relief under
