10. John Wayne Gacy, aka “The Killer Clown”
We are starting off our list of most evil serial killers ever with Gacy, from Chicago, Illinois, who was bullied by his schoolmates and father as a child for being unfit and made to feel like a failure, a sensation which grew into self-hatred and the rejection of his homosexual impulses. A beloved neighbor, he frequently entertained children’s parties as his alter ego “Pogo the Clown”. Having worked as a fast food restaurant manager in the 60s, he was accused of sexually abusing several young boys and even spent a couple of years in jail for it, but it was not until he got out that the killings began. Under the promise of construction work, he lured his victims, mostly teenage boys, into his home, where he sexually assaulted them and then strangled them with a rope, sometimes dressed in his costume. He then buried the bodies underneath the house, causing a foul smell, which raised suspicion. Pogo was convicted for 33 murders between 1972 and 1978 and sentenced to death by needle, making it into the 10 most evil serial killers ever.
See? I told you clowns were scary.
