Understanding Evil | The Story of God

To understand why evil exists, we have to know where it comes from. Some faiths see it as an unseen force that pervades the entire world—demons that lurk in the darkness. For Christianity, it could be the Devil Himself. Or is evil something that comes from inside us?

So, I'm traveling to a maximum security prison to meet a man you could call evil incarnate. "Skin, have you ever come face to face with evil?"

"I've met some people who've done some very bad things," neuroscientist Dror Kent Keel is trying to pinpoint the source of evil inside the brains of psychopathic killers. "I wanted to try to understand why people do really bad things—how to help prevent it someday."

Thank you. I'm about to meet one of Dr. Keel's most notorious subjects. He's serving a life sentence here. His attorney tells me this man raped more than two dozen women and murdered three. He's been in jail almost since he was a teenager, except for very short spurts, when he would get out of jail, he would go back to the same behavior of raping, and eventually it evolved into murder.

"Did he confess to these?"

"He confessed to all of them."

I'm not going to show you his face because I don't want to give any more notoriety to the man who committed these atrocities. But I want to know what can make someone do what he did.
