"I was born with the devil in me. I could not help the fact that I was a murderer, no more than the poet can help the inspiration to sing...I was born with the evil one standing as my sponsor beside the bed where I was ushered into the world, and he has been with me since."
H.H Holmes

"When this monster entered my brain, I will never know, but it is here to stay. How does one cure himself? I can't stop it, the monster goes on, and hurts me as well as society. Maybe you can stop him. I can't."
BTK killer (Dennis Rader)
