Sonny Elliman (biker tough guy) in Dead Zone

I started a thread about this a couple years ago, on IMDB, and someone just responded to it today. I am not sure what to think about this idea, but I have had a theory, off and on, that Sonny Elliman was originally supposed to be some sort of demon or devil. Maybe in am earlier draft of the book, or the screenplay for the movie. Anyone have any thoughts about this??? You can say what you think here, or on that thread.

Greg Stillsom seemed very ANGRY, and crazy, and bad to have in politics. But Sonny E was sort of mysterious, and I wondred if, somehow, he was originally concieved as a devil with whom Stillson cut a deal to be president.
