Yesterday's Gone question

I'm looking for a list of books that have a person that is living, breathing evil. Books that are told from this character's perspective, preferably first person but 2nd or 3rd will do. The more detail in the acts against other humans the better. I want to hate them the more I get to know them.

One example would be Boricio Wolfe in the Yesterday's Gone series. He's a serial rapist and killer.
