delivered the opinion of the court:
On November 24,1980, a criminal proceeding commenced in Peoria County. Victor King, the defendant, stood trial for the offense of burglary (Ill. Rev. Stat. 1979, ch. 38, par. 19 — 1(a)). After two days of testimony, the jury returned a guilty verdict. Later, defendant was sentenced to the penitentiary for 10 years. This appeal, which follows, presents the single issue of disparity of sentencing.
Both the defendant Victor King and a co-defendant, Reginald Davis, were initially charged with burglary. Prior to trial, Davis and his attorney negotiated an agreed disposition with the state’s attorney. In exchange for Davis’ plea of guilty to an amended information charging theft, it was agreed that the burglary charge against Davis would be dismissed. Davis agreed to a four-year penitentiary sentence. Sentencing hearing was waived.
Citing People v. Godinez (1980), 92 Ill. App. 3d 523, appeal allowed (1981), 85 Ill. 2d 17, defendant King contends that the sentence imposed on him is excessive. That disparity in sentencing exists here is clear on its face. Both King and Davis were participants in the same burglary/theft. Davis pleaded guilty to theft and received a four-year sentence. King stood on his not-guilty plea, was convicted of burglary by a jury, and was *258sentenced to 10 years in the penitentiary. The question on appeal is: Is the disparity justified?
Trial testimony indicated that defendant et al. entered the Tobin Brothers’ plumbing warehouse in Peoria on or about September 18,1980, and stole some microwave ovens. Access was gained by use of a crowbar. Once inside, the defendant and another passed the ovens to an unidentified person(s) standing on the other side of the fence which surrounds the Tobin premises. The value of the ovens was $9,000. Defendant King was identified by an eyewitness as the person who gained entry into the building with the crowbar.
At defendant’s sentencing hearing the “rap sheet” of Reginald Davis, listing prior arrests and convictions, as well as the record of the latter’s guilty plea in connection with the Tobin burglary, were admitted into evidence. Defendant argues that Davis’ criminal past and his were largely the same. The same argument was advanced as to each defendant’s participation in the crime. Also, the defendant alleged, the value of the stolen merchandise was inflated. Defendant admitted to a drug problem. Defense counsel recommended a sentence of four to five years’ imprisonment.
In this cause the record fails to reflect most of what defendant says it does. In pursuing his guilty plea, Reginald Davis did not offer any evidence at his sentencing hearing. Thus, such proceedings relate nothing about the man’s education, familial, or psychological history. How then can a comparison be made between such facts of defendant’s rehabilitative potential and those of Davis? Such cannot be done. Although we agree that previous criminal history may be highly relevant in assessing the likelihood of rehabilitation, such is not the sole factor of import in the sentencing equation (Ill. Rev. Stat. 1979, ch. 38, par. 1005 — 4—1). Appellate counsel overlooks the fact that defendant’s trial lawyer even argued that a disparate five-year prison term would be permissible.
The degree of King’s participation in the crime was not the same as Davis’. King used the crowbar to force his way into the warehouse. He was identified as passing the ovens to a third person who took them away. If he was not the leader in this felony offense, it is beyond argument that he was a principal participant in its commission. The record does not show the level of Davis’ participation in the burglary. Moreover, defendant’s attempt to depreciate the cost of the stolen merchandise does not control the gravity of the offense. This is especially so, where, as in the case at bar, the only rebuttal evidence of such cost was the defendant’s trial lawyer’s opinion as to its fair market value.
Defendant also fails to appreciate the distinction that Davis pleaded guilty to theft, whereas defendant was convicted of burglary. Although *259both offenses are felonies, our legislature has determined the latter is more serious (Ill. Rev. Stat. 1979, ch. 38, par. 1005 — 8—1). Defendant’s argument, followed to its logical conclusion, would lead to King’s receiving the same sentence imposed on Davis even if Davis had received a term of probation. In short, the argument runs, whatever a previous judge concludes is a just sentence as to one co-defendant controls the subsequent disposition of a different co-defendant if both parties are “similarly situated.” Supposing Davis had been allowed to plead guilty to the misdemeanor offense of trespass to land or disturbing the peace? Would such a disposition control the sentence for a co-defendant convicted of burglary? Presumably, we are asked to conclude that the prior sentence would control a latter sentencing disposition, even if the latter punishment imposed is prohibited by the sentencing statute.
What does such a theory do to a grant of immunity to procure testimony against a co-defendant? Could any greater disparity exist than a grant of immunity to convict a co-defendant? The logical extension of defendant’s argument would serve to defeat the purposes of the sentencing statute and the ends of justice. The sentence is supposed to fit the crime and the criminal and to take into account the interest of the public in the due administration of criminal justice. There is no basis in law for an artificial mandate that two defendants involved in the same offense must receive the same sentence.
A longer sentence is not unfair because of the length of its term if it is based on valid sentencing factors in aggravation and mitigation. The length of his sentence may be viewed by the defendant as an index for gauging whether his sentence, as well as his trial, was fair. A defendant’s personal assessment of the term of the sanction imposed, however, is not the operative fact upon which to determine whether a sentence is excessive.
At the sentencing hearing the circuit judge noted the defendant’s four prior felony convictions, two of which involved the same offense for which he had just been convicted. Both such offenses occurred within the previous 10 years. He considered mitigating circumstances, as well as the rehabilitative potential of the defendant. Also, he admitted as evidence the material concerning co-defendant Davis, which allegedly had a bearing on the disposition of defendant King. We do not believe defendant’s sentence is impermissible based on what transpired either at defendant’s sentencing hearing or the criminal proceedings concerning Davis’ plea of guilty. The trial judge explained the statutory considerations which were the basis of his imposition of an extended term (Ill. Rev. Stat. 1979, ch. 38, par. 1005 — 8—2). Obviously, the trial judge thought the rehabilitative potential of King was a severe risk to the community. In *260other words, his chances for reforming himself within a short prison term were minimal. The sentence of 10 years was within the statutory range of permitted penalties. No abuse of discretion occurred.
One factor that a trial judge takes into account in sentencing is a defendant’s rehabilitative potential. In this connection, it must be borne in mind that Reginald Davis pleaded guilty. Victor King has never admitted his complicity in the crime. Though it may be error of constitutional magnitude to impose a harsher sentence on King for invoking his right to a jury trial (People v. Sivels (1975), 60 Ill. 2d 102, 104), such is not the issue this cause presents. Defendant has adduced no evidence that his sentence was more severe because he sought a jury trial. Lacking such an affirmative showing, a sentencing disposition which is more favorable because of a co-defendant’s guilty plea does not prejudice the other co-defendant’s right to elect a jury trial. Defendant has never acknowledged his complicity in the burglary; Davis’ guilty plea, implicitly, if not actually, does so. If rehabilitation is to occur, an acknowledgement of guilt by the offender is the initial step to so-called rehabilitation. A guilty plea, most significantly, exhibits a defendant’s willingness to assume responsibility for his own conduct. A trial court can, quite properly, consider a declaration of guilt as evidence of the onset of rehabilitation and make concessions in sentencing. This in no way affects the rights of a co-offender who refuses to plead guilty but invokes a right to trial by jury. Merely because one co-offender is not penalized as severely because he admits his wrongdoing violates no rights of a co-offender charged with the same crime. Where one party admits wrong, but the other does not, and is subsequently convicted by his peers, it is inaccurate to contend that both persons are similarly situated with respect to the rehabilitative principal as concerns sentencing.
Sentencing determinations are complex and challenging. To be fair to a defendant, and the community within which he must dwell, a just punishment must address the activity done, the likelihood of rehabilitation or further criminality by the actor, and the effect the crime has on society. The sanction imposed will only be fair when all sentencing factors are balanced. Recognition of the sentence imposed on a co-defendant should also be weighed if properly before the court (Ill. Rev. Stat. 1979, ch. 38, par. 1005—4—1(b)). But such other penalty does not control the latter sentencing determination. Rather, it amounts to another component to be considered by the judge sentencing the defendant before him.
Rarely will a trial judge be confronted with two co-defendants who are really similarly situated in terms of the wrong committed, their individual histories and personalities, or their disposition with respect to *261the criminal justice system (cf. People v. Kline (1981), 99 Ill. App. 3d 540, with People v. Dewaele (1981), 98 Ill. App. 3d 636). This cause presents yet another scenario which accents the intrinsic distinction between two or more co-defendants. Furthermore, it exemplifies that to conclude, as a matter of law, that two co-defendants are similarly situated demonstrates a lack of actual analysis. The law demands more than a mere paper comparison couched in the terminology of principles of equal protection of the law. Defendants are not machines which can be calibrated or categorized for the purpose of legal argument. We should not expect trial judges to act as automatons when meting out punishment to a person who has been convicted of a crime. To conclude otherwise is to ignore the present realities which exist in our trial courts in the daily administration of justice.
Finally, we must address the question in the case of co-defendants, even if we are to assume perfect similarity, of whether the lesser sentence is correct. If the lesser sentence is incorrect, there is no justification in reducing a larger but correct sentence to coincide with the incorrect sentence. Two wrongs do not make a right. If, for instance, co-defendants who are similarly situated are charged with murder and one is allowed to negotiate a plea to a curfew violation and fined $10 for the offense, is the co-defendant who is sentenced to 20 years in the penitentiary for murder entitled to have that sentence reduced to a $10 fine? One would hope to the contrary.
For the reasons stated, the conviction and sentence of the Circuit Court of Peoria County are hereby affirmed.
Affirmed.
