What character out of all books, films and theater reminds you the most of yourself?

Director Hummel from Strindberg's "Ghost Sonata"
 

Not for his sexual indiscretions but his mind, the way he learns things and then wishes to use the ensuing knowledge for twisted and self-serving purposes. Hummel is a manipulative and life-sucking puppet master who murders and aggressively steals information to achieve anything that he desires. Without a few experiences changing the path of least resistance in my life I would be exactly like him... or am I exactly like him now?
