What are some characters that are just so nasty you are drawn to them?

Recently I read a book where a fairy godmother turned power hungry and turned the whole kingdom into her personal "perfect" fairy tale, despite the people's personal wishes. She was the antagonist, yet I really liked reading into her character because she was so deep. Her psychology fascninated me because her actions were twisted and "evil", yet she was driven by such strong reasoning to make everything "good."

I think this makes for very interesting and almost relatable bad guys in stories and novels, and I'm wondering if you have ever read a story with a striking good/bad antagonist.

I often think the "villain" is more interesting than the hero, particularly since they get a better back story. I have to say, I loved Snape in the Harry Potter series because he could always be counted on for a good one-liner. It got even better when they cast Alan Rickman to play him in the movies. I would say I don't read a lot of books that would necessarily have a bad guy, but I do love the twisted, conflicted villains in television and movies. Have you watched Once Upon a Time? Rumplestiltskin/Mr Gold is a fascinating character. He can be good one moment, than evil the next, and utterly self serving at other times, yet he's my favorite character over someone like Snow who is good all of the time.

"Love to hate" doesn't necessarily for me mean "so nasty that I'm drawn to them" but I get what you mean.

But I still love to hate Cedric Fauntleroy, only because the narrator keeps trying to shove it down my throat that he's perfect and I should love him because everybody loves him. I'm more of a Mary Lennox kinda girl: quite contrary!
