I accepted the fact I always like the villians a long time ago. Hell, when you're a 5 year old girl watching Star Wars for the first time and your favorite character is Darth Vader, there's not much to be done about it. :D I have no regrets about it. In my opinion, with very few exceptions, villians are always the more interesting characters and it pisses me off that they always wind up being killed off stupidly, or (worse yet) turn good.

I know what you mean about the fics though. Some fandoms have a good amount of awesome fics about the villians, but some are pathetically lacking.
