Who is the best villian or love-to-hate character?
Bellatrix Lestrange from the Harry Potter series. She's so crazy, but it's her craziness that makes her a love-to-hate character. I don't like that she tortured Neville's parents to insanity or that she tortured Hermione (fortunately not to insanity). I don't like that she's a Death Eater bent on killing Muggles, foxes (as seen in Half-Blood Prince), and Harry Potter. It's the development of her character and her infatuous love for Voldemort that makes her such an interesting and love-to-hate character.
