Getting a peek inside the mind of a serial killer is simultaneously fascinating and horrifying. These societal outcasts have a unique, twisted view of the world, and their words are often chilling.

Just try not to shudder as you read these creepy quotes from convicted serial killers:

1. Carl Panzram (1892-1930)

“I believe the only way to reform people is to kill them.”

2. Jane Toppan (1854-1938)

“That is my ambition, to have killed more people – more helpless people – than any man or woman who has ever lived.”

3. Albert Fish (1870-1936)

“I always had the desire to inflict pain on others and to have others inflict pain on me. I always seemed to enjoy everything that hurt. The desire to inflict pain, that is all that is uppermost.”

4. Aileen Wuornos (1956-2002)

“To me, this world is nothing but evil, and my own evil just happened to come out ’cause of the circumstances of what I was doing.”

5. Dennis Rader (1945-)

“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 he hurts me as well as society. Maybe you can stop him – I can’t.”

6. Edmund Kemper (1948-)

“I remember there was actually a sexual thrill…You hear the little pop and pull their heads off and hold their heads up by their hair, whipping their heads off, their body sitting there, that’d get me off.”

7. David Alan Gore (1953-2012)

“All of a sudden I realized I had just done something that separated me from the human race and it was something that could never be undone, I realized from that point on I could never be like normal people.”

8. David Berkowitz (1953-)

“I was literally singing to myself on the way home…The tension, the desire to kill a woman, had built up in me to such explosive proportions that when I finally pulled the trigger, all the pressures, all the tensions, hatred, just vanished, dissipated, but only for a short time.”

9. Gary Ridgway (1949-)

“I don’t believe in man, God, or the Devil. I hate the whole damned human race, including myself.”

10. John Wayne Gacy (1942-1994)

“A clown can get away with murder.”

11. Henry Lee Lucas (1936-2001)

“Sex is one of my downfalls. I get sex any way I can get it. If I have to force somebody to do it, I do…I rape them; I’ve done that. I’ve killed animals to have sex with them, and I’ve had sex while they’re alive.”

12. Ian Brady (1938-2017)

“We do whatever we enjoy doing. Whether it happens to be judged good or evil is a matter for others to decide.”

13. H.H. Holmes (1861-1896)

“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.”

14. Jeffrey Dahmer (1960-1994)

“My consuming lust was to experience their bodies. I viewed them as objects, as strangers…It’s hard for me to believe that a human being could have done what I’ve done.”

15. Peter Kurten (1883-1931)

“After my head has been chopped off, will I still be able to hear, at least for a moment, the sound of my own blood gushing from my neck? That would be the pleasure to end all pleasures.”
