Many multiple murderers blame our violent culture for feeding their appetites. Days before he was executed, Bundy declared that hard-core pornography was responsible for his murderous rampage. In our entertainment, sex and violence seem to go hand in hand.
Many serial killers adopt violent figures as their role models.
Both John Wayne Gacy and Ed Kemper worshipped John Wayne, who obviously had a broader fan base than only serial murderers, but his vigilante justice appeals to the killer who feels he has been wronged. To this day many homicidal acts are blamed on movies and music. Although there is no direct proof that violence in the media creates serial killers, it may activate the fantasy, and perhaps legitimizes it for some. Reared in a civilization which legitimizes violence as a response to frustration, provided by the mass media and violent pornography with both the advertising proclaiming the 'joy' of sadism and the instruction manual outlining correct procedures, they grasp the 'manly' identity of pirate and avenger. It is easier for us to see each other only as strangers, or stereotypes.
