390 P.2d 381], that there should he an exception to the normal standard of proof at the trial on the issue of penalty (People v. Purvis, 56 Cal.2d 93, 95 [13 Cal.Rptr. 801, 362 P.2d 713]). Thus, even though at the trial on the issue of guilt the jury must only be convinced that it is more probable than not that the defendant committed other crimes before it may consider them (People v. Albertson, 23 Cal.2d 550, 579, 581 [145 P.2d 7]), at the trial on the issue of penalty they must be convinced beyond a reasonable doubt.
Finally, defendants contend that the trial court must instruct on the legal considerations that the jury should take into account when deciding whether the penalty should be death or life imprisonment. We do not agree that such an instruction is compulsory. The Legislature has entrusted to the absolute discretion of the jury the awesome decision between life imprisonment and the death penalty in first degree murder cases. (Pen. Code, § 190; People v. Green, 47 Cal.2d 209, 218 [302 P.2d 307].) The Legislature has thus indicated its belief that jurors understand the factors that are relevant to such a decision. Recitation of such factors by the trial court is therefore not essential. The trial court, may, however, properly aid the jury hy stating the kinds of factors that may be considered, thereby setting the tone for the jury’s deliberation. (See People v. Friend, 47 Cal.2d 749, 767-768 [306 P.2d 463]; Model Penal Code, § 210.6 (Proposed Official Draft 1962).) In this case, the trial court erroneously instructed that the jury cannot be influenced by “pity for the defendant” or “sympathy” for him. (CALJIC No. 1.) Although appropriate on the issue of guilt, this instruction improperly eliminates factors that a jury may consider- in fixing the punishment. (See People v. Friend, supra, 47 Cal.2d 749,767-768.)
Since other questions raised are not likely to arise on retrial, we need not decide them here.
The remittitur in People v. Ronald Howard Polk and George Anthony Gregg, Crim. No. 7356, 61 Cal.2d 217 [37 Cal.Rptr. 753, 390 P.2d 641], is recalled and the judgment of the Supreme Court of March 31, 1964, vacated as to defendants Polk and Gregg. The judgments appealed from are reversed in their entirety.
