Take Ted Bundy for instance. The guy is a well known celebrity with a large fan club, but the innocent, young girls he raped, mutilated, and murdered are all but forgotten.
People still talk about Charles Whitman for climbing into a tower and massacring unarmed pedestrians, but don't even know the names of the men who volunteered to enter the tower and apprehend him.
I cannot even turn my television on without seeing something about Hitler or his regime, or a murder investigation, cold case files etc. It's really depressing to know that you would be more loved, and remembered for going out and shooting 100 kids (Oslo instance) than you would ever be for devoting your life to helping others.
