What is the purpose of victim impact evidence in a murder case?

"The purpose of victim impact evidence is to demonstrate the immediate harm caused by the defendants criminal conduct." ( People v. Pollock (2004) 32 Cal.4th 1153, 1183, 13 Cal.Rptr.3d 34, 89 P.3d 353.) That harm is not limited to immediate family members. ( People v. Williams (2015) 61 Cal.4th 1244, 1285, 192 Cal.Rptr.3d 266, 355 P.3d 444.) Friends, coworkers, classmates, and teachers, may all be affected by the death of the victim
