He(his neighbor's "possessed" dog)won't let me stop killing until he gets his fill of blood." -David Berkowitz
"I am a monster. I am the Son of Sam. I love to hunt."
"I always had a fetish for murder and death."
"I have several children who I'm turning into killers. Wait till they grow up."
"I turn children into killers."
"I didn't want to hurt them, I only wanted to kill them."
"I was literally singing to myself on my way home, after the killing. The tension, the desire to kill a woman had built up in such explosive proportions that when I finally pulled the trigger, all the pressures, all the tensions, all the hatred, had just vanished, dissipated, but only for a short time."
"I wasn't going to rob her, or touch her. I was just going to kill her."
"In this hole lives the wicked king."
"Kill for my masters."
"The demons wanted my penis."
