On the one hand, I know for a fact that evil entities/demons/jinns, whatever you want to call them, exist. I call them as a group "The Dark Side," and they are real beings. I'm always grinning about people who want to restrict them to the realm of psychology, as in "the evil that lives in every person's psyche" or something. I've encountered too many of them to think they're just some figment of our subconscious.
On the other hand, I don't know if they really have a "leader" in the sense of Satan as a personified being. If so, my vote would probably go to the "Hat Man," whom some people who've seen him have described as the devil himself.
Heidi Hollis once told a story on C2C AM, about a military guy who tried to commit suicide and woke up in a hospital bed. He found the Hat Man sitting on his bed saying, "I almost had you." If that's true, it would be in line with the lore about suicides going to hell... but really, who knows for sure?
