How have the courts treated evidence of good character and even temper in a criminal case?

Although defendant proffered only a single statement from one witness, that testimony was nonetheless a broad and general statement asserting defendant's good character and even temper. While the prosecution offered much more and much stronger rebuttal testimony than the comparatively tepid character evidence proffered by defendant, this does not render the evidence inadmissible. For example, testimony that the defendant was a devout Buddhist, and truth or honesty are characteristics of devout Buddhists, could be met by evidence of defendant's prior convictions from Thailand which involved dishonesty. (People v. Siripongs (1988) 45 Cal.3d 548, 576-578.) Defendant does not contend on appeal that the evidence should have been excluded pursuant to Evidence Code section 352. Therefore, the relative strength of the rebuttal evidence does not preclude its admission.
