I can be an angsty, angry little beast. There is a lot of opinionated bottle up in this not-so-tiny body of mine. I would most probably drive the reader insane if I were to model the protagonists, who anyways get all the airtime, after me. This is assuming people read my work of course.
Some authors can pull a Raskolnikov character off amazingly (like, uh, Dostoevsky, the guy who invented Raskolnikov) as a protagonist. I couldn't. Antagonist it is, baby.
