JUSTICE HEIPLE
delivered the judgment of the court:
Following a jury trial in the circuit court of Livingston County, defendant, Evan Griffith, a prison inmate, was convicted of first degree murder and unlawful possession of a weapon by a person in the custody of the Illinois Department of Corrections. (Ill. Rev. Stat. 1989, ch. 38, pars. 9 — 1(a)(1), (a)(2), 24 — 1.1(b).) He was sentenced to death on the murder conviction and to a consecutive 30-year prison term on the weapon conviction. The death sentence has been stayed (134 Ill. 2d R. 609(a)), and the case is now before us on direct appeal (Ill. Const. 1970, art. VI, § 4(b); Ill. Rev. Stat. 1989, ch. 38, par. 9 — 1(i); 134 Ill. 2d R. 603).
State’s Evidence
The State’s evidence at trial was essentially as follows. Defendant and the victim, James Jones, also known as Joseph Moore, and Wilford Mackey were all inmates at the Pontiac Correctional Center in Pontiac, Illinois. Additionally, they were all members of the Black Gangster Disciples street gang. Jones was the Institutional Coordinator (I.C.) of the Black Gangster Disciples within the Pontiac Correctional Center. The I.C. is the leader of a street gang within a prison. The defendant, Evan Griffith, served as Jones’ personal secretary and "bodyguard.” Due to his position within the gang, he was required by the gang to carry a weapon.
On the morning of October 2, 1990, Jones, Griffith and Mackey were in the prison’s south yard. At approximately 11 a.m., Jones was talking on a telephone at a bank of telephones in the yard. While he was on the telephone, Mackey approached him from behind and repeatedly struck him on the head with a metal rod or pipe. Jones dropped the telephone and, unarmed, attempted to defend himself. Griffith then stabbed Jones once in the chest with a "shank.” Jones fled but soon collapsed and died. The stab wound was the cause of death.
Defendant’s Evidence
The defense theory was self-defense. Defendant claimed that on the night before the stabbing, he received a message that Jones wanted to see him. Defendant sent word that he could not meet with him that night, but would see him the next day. Jones apparently became upset with defendant when he failed to come when summoned. On the following day, defendant attempted to clear things up with Jones. Defendant claims that he tapped Jones on the shoulder while he was on the telephone. Jones angrily ordered defendant to leave him alone and, a few seconds later, produced a shank.
Defendant then produced a shank and took two steps back. Jones dropped the telephone and stepped towards defendant, bobbing and weaving. At the same time, defendant was jabbing his shank towards Jones to repel him. Jones quickly ducked down. When he came up, defendant’s shank penetrated his chest. Both Jones and defendant dropped their knives. Defendant did not intend either to stab or to kill Jones.
The Verdict
At the close of the trial, the jury convicted defendant of first degree murder and unlawful possession of a weapon by a person in the custody of the Department of Corrections.
Defendant waived a sentencing jury. In the first phase of the sentencing hearing, the trial judge concluded that defendant was eligible for the death penalty because the victim was a prison inmate killed on prison grounds.
During the second phase of the sentencing hearing, the State presented evidence in aggravation and defendant presented evidence in mitigation. The trial judge found that death was an appropriate sentence for defendant and that there were no mitigating factors sufficient to preclude the imposition of the death penalty. Accordingly, he sentenced defendant to death on the first degree murder conviction and to a consecutive 30-year prison term on the inmate weapon possession conviction.
Defendant appeals. Additional pertinent facts will be discussed in the context of the issues raised on appeal.
DISCUSSION
On appeal, defendant claims numerous errors, all without merit. He further claims that the Illinois death penalty statute is unconstitutional. We affirm.
While we will address defendant’s contentions on the merits, most of the issues have been waived since either no objection was made at trial or the issues were not properly preserved in a post-trial motion. As to several of the alleged errors, neither an objection nor a post-trial motion was made. People v. Enoch (1988), 122 Ill. 2d 176.
Defendant alleges error since the State insinuated that defendant had a gang-related motive for committing the murder. The evidence brought forth by the State and the defense established that Jones held the position of "institutional coordinator” in the Black Gangster Disciples. While cross-examining defense witness Kevin Walton, who is also an inmate at the Pontiac Correctional Center and a member of the Black Gangster Disciples, the following discussion took place:
"[PROSECUTOR]: After James died, was a new I.C. selected?
[WITNESS]: No.
[PROSECUTOR]: They never replaced James as the institutional chief?
[WITNESS]: Not in ’90.
[PROSECUTOR]: Who is the I.C. now?
[WITNESS]: I don’t know.
íjí
[PROSECUTOR]: Did you know an inmate by the name of Mackey?
[WITNESS]: Yes.
* * *
[PROSECUTOR]: Is he a friend of yours?
(WITNESS]: I wouldn’t say that. I said I knew him.”
Defendant contends that based upon this line of questioning, the jury, without supporting evidence, was led to believe that the defendant killed Jones so Mackey could take over as I.C. of the Black Gangster Disciples. This argument is without merit. Mackey and defendant were both implicated in Jones’ death. Merely asking Walton who the current I.C. is, and asking him whether he knew Mackey, does not improperly insinuate to the jury that Mackey sought to benefit from Jones’ death.
Defendant was asked on cross-examination to give the name of the gang official who was above Jones in the Black Gangster Disciples’ organizational structure. Defendant refused to answer the question. By looking at sidebar discussions which took place outside the presence of the jury, defendant points out that the State thought that defendant may have been ordered to kill Jones. Thus, defendant argues that he was prejudiced in front of the jury since these allegations were never substantiated. However, the State did not pursue this line of questioning in the presence of the jury. Once the defendant refused to answer who was in charge of the gang, this line of questioning ended and no improper insinuations were made to the jury. The defendant cannot base a claim of prejudice upon statements which were made outside of the jury’s presence.
Defendant’s next contention of error is that the prosecutor, in closing argument, improperly suggested that the defendant had threatened and intimidated two witnesses for the State. Witnesses Marzette and Cleveland, both inmates at Pontiac Correctional Center, upon initially being interviewed about the attack upon Jones denied knowing anything. On the next day, they admitted that defendant was one of the attackers. Both Marzette and Cleveland testified that the reason they initially denied seeing anything was because there is a "code of silence” in prison. They described the "code of silence” as when one organization (gang) does something, then regardless of whether or not you are in that organization, you do not talk about what happened. In closing argument, the prosecutor reminded the jury that while Marzette and Cleveland initially denied having any knowledge about the attack on Jones, they both stated the reason for their denial was the "code of silence.” The prosecutor added that Marzette and Cleveland had to face being confined in the same cell house with the same individuals who were responsible for the attack. Defendant contends that these comments conveyed to the jury that the witnesses had been threatened by him. Contrary to defendant’s assertions, the prosecutor did not suggest that the defendant had threatened the witnesses. Rather, he merely reminded the jury of the "code of silence” which they had already heard about.
Defendant also claims that the prosecutor improperly elicited testimony from Marzette and Cleveland that they had been threatened by fellow inmates due to their involvement in this case. Inmates Marzette and Cleveland both testified on direct examination that after they identified the defendant, they were moved out of Pontiac and into other prisons. Additionally, they both stated that due to their involvement in this case they had been threatened by other inmates in their new locations. Defendant contends that this testimony was prejudicial and improper since the jury was led to believe that the threats emanated from him. Contrary to defendant’s assertions, the prosecutor made no references of this type. Rather, the threats which were made upon Marzette and Cleveland illustrated to the jury that the "code of silence” is an actual code of conduct within prisons. Since the jury was aware of the "code of silence,” this testimony was not unduly prejudicial to the defendant.
Defendant further alleges that the prosecutor improperly elicited victim impact testimony from the victim’s wife. Defendant points out that Innie Jones, the widow of James Jones, testified that she and Jones had been married for 18 years, they had three children and that the children and the victim loved each other. Defendant also relies upon the fact that in closing argument, the prosecutor told the jurors that they did not have to like the victim, but he was a human being, a son, a father, and a husband, and that no one has the right to take somebody’s life for no legal reason. Defendant was not prejudiced by these comments. Mere mention of family relationships does not necessarily result in prejudicial error. From Innie Jones’ testimony, defendant takes three questions out of context and claims that the prosecutor intentionally elicited this testimony with the purpose of inflaming the jury. This is not the case. The prosecutor was merely establishing a foundation for Innie Jones’ testimony. Additionally, after the prosecutor asked about the victim’s relationship with his children, the trial judge stopped the questioning in regard to family relationships. After this, no more mention was made to the jury concerning the victim’s family. Defendant failed to object to any of the questions at trial and has now failed to show that the prosecutor was intentionally attempting to inflame the jury. This court has recognized a distinction between making a jury aware of the family left behind and cases where the prosecution has dwelled upon the victim’s family to the point that the jury could have related that evidence to the defendant’s guilt. People v. Lear (1991), 143 Ill. 2d 138, 150; People v. Del Vecchio (1989), 129 Ill. 2d 265, 288.
JURY INSTRUCTIONS
At the close of the evidence, the trial judge held a jury instruction conference. Present were the defense counsel, the defendant himself, and the prosecutor. During the jury instruction conference, the following colloquy occurred:
"[THE COURT]: [A]nd I wish to at this time, before launching into definitions or issues in a murder case, advise Mr. Griffith of the following: His attorney may request, but it’s a decision that only defendant can make, as to whether the Court should give instruction to the jury on what in Illinois is called second degree murder.
In Illinois, a first degree murder is defined when a person kills an individual if, in performing the acts which cause the death, he intends to kill or do great bodily harm to that individual or another; or he knows that such acts will cause death to that individual or another; or he knows that such acts create a strong probability of death or great bodily harm to that individual or another.
It is possible in Illinois for a jury to find a defendant guilty of what is called second degree murder. Many years ago it used to be called voluntary manslaughter, but there has been some changes in what the definition is.
* * *
*** [I]f the State proves a first degree murder, but you would wish to argue to the jury, and if the Court found it was proper in this case, that at the time you performed the acts which cause the death of James Calvin Jones, also known as Joseph Moore, then that may be — or those may be factors which could reduce a first degree murder to a second degree murder.
In other words, in effect, the jury would be told that if they find that a first degree murder has been proven, but there were circumstances surrounding that first degree murder, specifically, that at the time the murder was committed, you were acting under a sudden and intense passion resulting from serious provocation by him, then those would be elements that could establish a second degree murder, and if I instructed the jury on that, then the State would have the burden of proving that beyond a reasonable doubt, that those reducing factors were not present and they would have to prove to the jury beyond a reasonable doubt that you did not act under a sudden and intense passion resulting from serious provocation. [We note that this is an incorrect statement of the law. The trial judge’s correction of this misstatement is included below.]
What would be serious provocation? If your attorney argued, and I permitted the jury to be instructed, I gather the evidence would be that serious provocation could be from the defense standpoint when you tapped the decedent on the shoulder and he turned and pulled out a shank, that that could be serious provocation. It also could relate to self-defense.
[DEFENSE COUNSEL]: Your Honor, I think that the defendant, contrary to our prior discussions, has concluded that he wishes me to tender that instruction. I don’t have one available right now. I would tell the Court that I do intend now to tender such an instruction and would ask the Court to rule on whether it would be given or not now. I will tender the standard Murder II.
* * *
[THE COURT]: Mr. Ahlemeyer, because I was assuming from a conversation before defendant was brought in that perhaps he didn’t want them instructed on second degree murder—
[DEFENSE COUNSEL]: I was too. I thought so, your Honor.
[THE COURT |: Let me tell you, Mr. Griffith, practically what it means to you. A second degree murder instruction telling them that they can consider that and telling them what they would have to find in order to find you guilty of second degree murder rather than a first degree murder.
Some defendants say: I don’t want to let the jury compromise the verdict. I believe I have a legitimate self-defense or I’m just simply not guilty, for whatever reason, as brought out in the trial, and I want them to make a decision that I’m either guilty of murder or I’m not and I don’t want to provide them with something that they may look at and could in effect compromise.
Sometimes people say the defendant is rolling the dice on all or nothing in the murder case, that either the jury is going to be forced to find a first degree murder or nothing and they don’t have any in between room because if they are not instructed that they can find something less than murder, first degree murder, then it’s all or nothing.
They wouldn’t be able to come back and say: We don’t agree on first degree murder, but we want to agree something other than that. They would not have any verdict forms for anything other than first degree murder and they couldn’t do that and they are faced with choosing between first degree murder or no murder by virtue of, in this case, self-defense.
If you give them a second degree murder instruction, *** the State would have to prove beyond a reasonable doubt that there were no reducing factors, there was nothing to kind of make it less serious murder, and that’s what we are talking about. [We note that the trial judge again misstated the law. His correction is included below.]
A second degree murder is still a murder. They find somebody guilty of murder, and then after they do that, if the defendant says: Yeah, but I was under a sudden and intense passion resulting from serious provocation by whoever got killed, and if the jury gets that instruction, then the jury has to find beyond a reasonable doubt that those factors that would lessen how serious it is are not present.
So, in other words, the State has to prove a negative. They have to prove that there was no serious and intense passion resulting from serious provocation by the dead person and they have to prove that to the jury beyond a reasonable doubt. If they can’t do that, then the jury, under the law would find a second degree murder. [Again, this is a misstatement of the law which is corrected below.]
So, it’s a decision that only you can make and it’s one where, in eifect, you are saying I will roll the dice, it’s all or nothing, or I would ask the Court to instruct them on what a second degree murder is knowing that they may come in with a second degree, and if you are convinced that it should be all or nothing, then that’s your choice.
If you aren’t convinced you want them to be told it’s all or nothing, I still have arguments to hear whether it’s proper to give that instruction, but that, to some people, is a compromise verdict and some defendants afterwards say: I was crazy. I found out afterwards the jury would never have found me guilty of a first degree murder and if they were faced with all or nothing, it would be [szc] nothing. Now look what happened. They came in with a second degree because they had that way to kind of wiggle around in it, but that’s up to you.
Your lawyer can’t make the decision. Only you can make the decision.
[PROSECUTOR]: Judge, I believe when you were telling him about the various burdens and the allocations of the burdens, I believe that you may have misstated or perhaps in my deafness I may have misunderstood what you said.
As I understand the burdens in a second degree, we have the obligation of proving first degree murder and then the defense had the burden of establishing, by a preponderance of the evidence, mitigating factors ***. [At this time the trial judge researched who maintains the burden of proof regarding the mitigating factors in a second degree murder charge.]
[THE COURT]: [The relevant statute provides that] [w]hen a defendant is on trial for first degree murder and evidence of either the mitigating factors *** has been presented, the burden of proof is on the defendant to prove either mitigating factor by a preponderance of the evidence before the defendant can be found guilty of second degree murder. However, the burden of proof remains on the State to prove beyond a reasonable doubt each of the elements of first degree murder and, when appropriately raised, the absence of circumstances at the time of killing that would justify or exonerate the killing ***.
Second degree murder is a Class 1 felony. The possible penalties for second degree murder would be a prison term for a period of years of anywhere from four to 15 years, or depending if the defendant is a repeat offender or it’s especially heinous or brutal, then it could be an extended term of 15 to 30 years.
So, Mr. Griffith, if you would be found guilty of second degree murder, the possible sentence range would be four to 15 years in the Illinois Department of Corrections or an extended sentence of 15 to 30 years and that would carry with it a two year supervised release or parole period.
* *
So, in other words, I told you before that in effect if I gave a second degree murder instruction, then the State would have to disprove beyond a reasonable doubt that there is serious provocation sufficient to incite an intense passion in you, a reasonable person, and they would have to disprove that *** James Calvin Jones, also known as Joseph Moore, did something to cause a sudden and intense passion ***.
In effect, I told you before the State would have to disprove that. The law is not that. The law is that you would have to show by what’s called a preponderance of the evidence a mitigating factor that you would be guilty of the lesser offense of second degree murder and the jury would have to find that it would be more probably true than not true that a mitigating factor was present and that at the time *** James Calvin Jones was killed *** you were acting under a sudden and intense passion resulting from serious provocation by him.
So, I will try and put it in layman’s terms. First of all, I told you what the possible penalty is for second degree murder. Do you understand what that is?
[THE DEFENDANT]: Yes, I do.
[THE COURT]: That’s prison time. There’s no possibility of a death sentence ***.
So if they came back with a second degree murder, you would be looking at consecutive prison time from four to 15 years or from 15 to 30; do you understand that?
[THE DEFENDANT]: Yes I do.
[THE COURT]: Now, in effect, if the jury is given instruction that they can find you guilty of second degree murder, what it means to you is that the State has to prove beyond a reasonable doubt that you committed a first degree murder, then you would have to show to the jury and the jury would have to find from the evidence in the case that it’s more probably true than not true that there was what’s called a mitigating factor, that the murder of James Calvin Jones, also known as Joseph Moore, occurred while you were acting under a sudden and intense passion resulting from serious provocation by him
So, what it really means is that if the jury said: Well, the State had proved that you intended to kill or do great bodily harm to James Calvin Jones or that you knew that your acts could, will cause his death or you knew that there was a strong probability of death or great bodily harm by thrusting at him with a shank, and therefore that constitutes a first degree murder, the jury then further, in looking at the evidence, if they found those elements of first degree murder proven beyond a reasonable doubt, could determine based on the evidence that if when the killing took place you were acting under a sudden and intense passion, there was serious provocation by the victim, then they could come back with a second degree murder instead of a first. It’s still murder; it’s a difference in the responsibility.
Do you follow what I’m saying there?
[THE COURT]: And that would be up to you through the evidence presented in the case and in the arguments of your attorney to show them that. Okay.
And some people have argued in higher courts that it’s not fair to make you prove that you are less culpable or less responsible because of the circumstances, that the burden ought to stay on the State and this statute has been upheld and it did change the law in Illinois and puts some burden on your side to show that it was — that it was a second degree murder rather than a first degree murder.
Now, I have gone through all of this, and in the meantime Mr. Ahlemeyer ¡defense counsel] says you have been thinking further and it’s your position, and I don’t know if it still is because we have talked about it for awhile, that you would like the jury only instructed as to first degree murder and not as to both first and second degree.
[THE DEFENDANT]: I think I would like the jury to consider the first degree or acquittal.
[THE COURT]: Okay. So, in other words, if we give them second degree murder instructions, that is considered kind of a compromise verdict, and the cases have talked about that, and if you go just for guilty or not guilty of first degree murder, the jury gets no information that they can in effect find you guilty of first degree, but then if they find this mitigating factor, in effect come back with second degree, that’s the risk you run in deciding I don’t want them instructed on second degree and that it’s all or nothing.
[THE DEFENDANT]: That’s right; that’s what I agree.
[THE COURT]: That’s a big decision for you and that’s one I can’t make, your lawyer can’t make for you, only you can make.
[THE DEFENDANT]: I have been weighing it and thinking about it all day. I have come up with the conclusion that it’s either one or the other, acquittal or a first degree.
[THE COURT]: I would indicate for the record that I believe the defendant has now been properly instructed that it would be the defendant [who] would have to show by a preponderance of the evidence it’s probably more true than not true — that there would be a mitigating factor.
I have told him in this case the mitigating factor, I assume, is his testimony that the victim turned, pulled a shank on him, and although these get into cross elements of self-defense and the jury will consider a self-defense to the first degree murder, but they could consider not only self-defense, but that it was a second degree murder.
Now those may not seem real consistent that you say in one breath: I was acting in self-defense and in the other breath — which would result in a finding of not guilty if the jury found self-defense, and then in the other breath say: Well, if you don’t find I was acting in self-defense, what he did in his conduct incited me and makes my responsibility somewhat less and it’s a second degree murder.
You are shooting for first degree murder with the defense of self-defense which would mean a not guilty if the jury finds self-defense or they are going to find you guilty of first degree murder, and if they find you guilty of first degree murder, only two ways to go, that would be death penalty or a natural life and those are the only two alternatives if you get found guilty of a first degree murder, and if they came back with a second degree then there’s no possibility of a death sentence or a natural life.
[THE DEFENDANT]: I understand, your Honor. I will take my chances.
* :fc *
[THE COURT]: Okay. So, we will have no series of instruction advising the jury of the definition of a mitigating factor for second degree murder and we will not instruct the jury on both first degree murder and second degree murder and they will be instructed only on first degree murder and the defendant, and I believe that he has thought this through, I believe he understands and I believe he understands he’s rolling the dice, It’s an all or nothing proposition, and that the court, I believe, would be willing to give both a first degree and second degree instructions, and he says: No, only give the first degree.
Mr. Ahlemeyer, are you satisfied he understands what’s going on?
[DEFENSE COUNSEL]: I believe he does.
[THE COURT]: All right.”
It has long been recognized that there are four decisions which belong exclusively to the criminal defendant to make after full consultation with his attorney: what plea to enter, whether to waive a jury, whether to testify on his own behalf, and whether to appeal. (Jones v. Barnes (1983), 463 U.S. 745, 751, 77 L. Ed. 2d 987, 993, 103 S. Ct. 3308, 3312.) These decisions cannot be denied him. Matters of trial tactics and strategy, on the other hand, belong to the lawyer. That is, not to say, however, that the converse is true. In other words, it is not error merely because the defendant himself may decide a matter of trial strategy rather than his lawyer.
In this case, the defendant was fully informed by the judge about the separate instructions of first and second degree murder. It is clear from the record that the defendant’s choice was voluntary, intelligent and knowing. In telling the judge that he did not want the second degree murder instruction to be given, the defendant stated: "I have been weighing it and thinking about it all day. I have come up with the conclusion that it’s either one or the other, acquittal or a first degree.” With his attorney present, the defendant chose not to instruct the jury on second degree murder. In other words, he wanted the jury to have but two alternatives: guilty of murder in the first degree or not guilty. He did not want to take the chance of a compromise verdict of murder in the second degree. He would go for broke. His attorney verified that the defendant understood what he was doing. Neither the defendant’s attorney nor the defendant objected to the judge’s directive that the defendant and not the attorney make this decision. Neither did the defendant’s attorney indicate in any way that he was of a different opinion or that the choice was unsound.
Now, however, having taken his chances and lost, the defendant claims, in hindsight, that it was error to require him to make this decision. We do not agree.
Defendant further incorporates into this argument that his counsel was somehow ineffective for not objecting on procedural grounds that the decision belonged to counsel exclusively. While it is true that no such objection was raised, a fair reading of the colloquy at the jury instruction conference causes us to conclude that defense counsel willingly acquiesced in and accepted both the directive to the defendant and the defendant’s wishes in this regard. There is no indication whatever of any difference of opinion between the defendant and his attorney as to the decision not to give the second degree murder instruction. We find no error here in the judge’s directive to the defendant to make this decision. It was a tactical decision to be sure. However, it is only in hindsight that the decision could be deemed unfortunate. Had the defendant chosen to ask for a second degree murder instruction and been convicted of that, he most assuredly would now be raising a similar objection, equally invalid.
Defendant’s final contention of error in regard to the jury instruction conference is that the judge gave incorrect, misleading, and coercive admonishment regarding the giving of a second degree murder instruction. Thus, defendant contends that he gave an unknowing and nonintelligent waiver of his right to have the jury instructed on second degree murder. Out of the entire jury instruction conference, which is essentially set out above, defendant takes a few isolated remarks out of context and gives them undue weight.
Defendant relies upon the following alleged errors: (1) the trial judge, although subsequently correcting himself, misstated the law regarding the burden of proof in establishing the mitigating factors for second degree murder; (2) the trial judge failed to state that a valid mitigating factor for the jury to consider in determining second degree murder is an unreasonable belief of self-defense; (3) the trial judge failed to state that the prosecution must disprove defendant’s affirmative defense of self-defense; (4) the trial judge told the defendant that theories of self-defense and second degree murder are inconsistent; (5) the trial judge referred to second degree murder as a compromise instruction; (6) the trial judge failed to expressly tell the defendant that an acquittal could occur even if the second degree murder instruction was offered; and (7) the trial judge confused the defendant by telling him that while the law in regard to second degree murder required him to prove that he was less culpable, arguments have been made that placing this burden upon the defendant is unfair.
All of these claims are without merit. A review of the jury instruction conference reveals that of these alleged errors, the trial judge himself either corrected the error, or the alleged comment or omission had no impact upon the jury instruction conference when viewing the conference in its entirety.
SENTENCING ISSUES
Defendant claims that he was denied his right to an individualized capital sentencing hearing. In support of this contention, defendant points out that he offered mitigating evidence from two prison educators, and a juvenile probation officer who had known the defendant for seven years. In essence these mitigation witnesses testified that in their dealing with the defendant they had found him to be polite, courteous, open to suggestion, and a good worker with fellow inmates. In commenting on this mitigation evidence, the trial judge stated that there is no question that the defendant while dealing with authority figures is a likeable inmate. The judge went on to note, however, that many inmates in Illinois are likeable, including some on death row. Defendant contends that these comments indicate that the trial judge refused to consider this evidence and thought that it had no mitigating value.
Prior to the imposition of the death penalty, an individualized assessment of the circumstances of the crime and character of the defendant must be made. (People v. Turner (1993), 156 Ill. 2d 354, 359-61.) Merely because mitigation evidence is presented, however, does not automatically render the evidence sufficient to preclude a sentence of death. Contrary to defendant’s assertions, the trial judge did not state that evidence of defendant’s "likeability” had no mitigation value. At the same time, however, it is reasonable for a trial court to conclude that a defendant’s good behavior in front of authority figures is not necessarily representative of his usual behavior. The trial judge properly considered defendant’s mitigation evidence, for whatever it was worth, and properly concluded that it was insufficient to preclude a sentence of death.
Defendant next claims that the trial judge, in sentencing defendant to death, erroneously believed that the ultimate responsibility for imposing the death sentence rested with the reviewing State and Federal courts. This contention is totally without merit and stems from a mischaracterization of the judge’s comments. In making some general comments on the death penalty and the seriousness of the decision he was making, the trial judge stated that due to the current conservative posture of both State and Federal courts, once a death sentence is imposed it is more likely than in the past that a defendant will actually be executed. The judge went on to note that this had been a terrible and agonizing decision for him to make. By looking at this comment in context, it is apparent that the trial judge not only understood that the ultimate responsibility for imposing the death sentence rested with him, but he also believed that defendant would be unable to stop his execution by way of legal maneuvers and that defendant’s life rested in his hands.
Defendant’s third and final contention of error in connection with his sentencing hearing is that the trial judge, in pronouncing defendant’s death sentence, relied upon information outside the record which the defendant had no opportunity to rebut or explain. As with defendant’s previous argument, this argument also takes the trial judge’s comments out of context. Defendant points out that at one point the trial judge remarked that if an inmate in the Illinois prison system commits a murder and is sentenced to natural life, generally that means that after serving one year of disciplinary segregation, the inmate will be released back into the general prison population. Additionally, the trial judge noted that without the death penalty there would be nothing to deter an inmate serving a life sentence from killing fellow inmates and prison officials. These comments were but one aspect of the judge’s articulation of his rationale for imposition of the death sentence and were not error. In rendering a sentence, a trial judge is presumed to have relied upon only competent and reliable evidence. Additionally, it is defendant’s burden to overcome this presumption. The defendant has offered no evidence, nor can we find any, that the trial judge’s rhetorical comments served as an improper basis for the death sentence. The record does reveal, however, that in imposing the death sentence the trial court explained that its decision was guided by specific statutory provisions. The trial judge noted that defendant had been proven guilty of first degree murder beyond a reasonable doubt and was found eligible for the death sentence since he killed a prison inmate on prison grounds. In aggravation, the trial judge noted that defendant had an extensive history of violent crime, including convictions for two residential burglaries and a brutal murder by use of a hammer and knives which he committed at the age of 16. It was based upon these factors that the death sentence was imposed.
CONSTITUTIONALITY OF THE DEATH PENALTY
Defendant finally contends that the Illinois death penalty statute is unconstitutional because it places a burden of proof on the defendant which precludes meaningful consideration of mitigation evidence, and because it does not sufficiently minimize the risk of an arbitrary or a capricious death sentence. These arguments have been previously addressed and rejected by this court. (See People v. Burrows (1992), 148 Ill. 2d 196, 259-60.) Defendant fails to persuade us to reconsider this court’s prior holdings.
CONCLUSION
For the above reasons, we affirm the judgment of the circuit court.
