Rita Bennett-Morgan from Dexter
Plenty of people were murdered on Dexter throughout the series, but Rita’s (Julie Benz) death was particularly devastating for titular character (Michael C. Hall). Not only did her ruthless murder at the hands of the Trinity Killer seem to parallel his mother’s death, but Dexter then realized that he was, in fact, capable of loving another human being. Rita’s demise served as a turning point for the serial killer.
