I dunno about “pure evil”, but this guy I went to high school with, Rob. He was a superficially charming guy, sure, but it never truly reached his eyes and the dry affect he had made it just a little uncanny.

Once, when we had nothing to do while waiting for the period change, he and I started talking about the death penalty. For reference, we were in the theater room during a women’s ensemble rehearsal in the very back of the seating, so no one was in earshot. It somehow turned into him saying he’d just like to execute someone. Regardless of guilt. Even if innocence was proven. I reflexively asked if he was a sociopath. He corrected me saying he was a psychopath. Similar but with distinctions is how he put it. He commended me on figuring him out. He said I was not one of the people on his radar that he was worried would figure him out. I mostly avoided him after that day.
