What constitutes prejudicial or damaging evidence in a criminal case?

flows from relevant, highly probative evidence. '[A]ll evidence which tends to prove guilt is prejudicial or damaging to the defendant's case. The stronger the evidence, the more it is "prejudicial." The "prejudice" referred to in Evidence Code section 352 applies to evidence which uniquely tends to evoke an emotional bias against the defendant as an individual and which has very little effect on the issues. In applying section 352, "prejudicial" is not synonymous with "damaging." ' [Citation.]" (People v. Karis (1988) 46 Cal.3d 612, 638.)
