I'm going to go over the top three scariest literary villains ever. The top three scariest that I can come up with at 2:00 am when I'm supposed to be reading The Iliad, anyway. Here we go!
1) Lord Voldemort. Super obvious, but who would disagree? The guy is so scary that people don't even use his real name out loud. He is terrifying because he's pure evil, no redeeming qualities. He doesn't understand love, so he doesn't understand positive emotions at all. He is like the ultimate definition of sociopath, except with magic, so that makes it even worse.
2) The Other Mother from Coraline. She really terrifies me, probably because she takes something familiar (ie your family) and changes them into something that can hurt you. But she does it under the guise of love. And she has BUTTONS for eyes, besides wanting to sew them into yours too! Plus, she can lock you in a mirror indefinitely. I think that's pretty scary.
3) Roger Chillingsworth from The Scarlet Letter. There are a lot of characters in that book that scare me, Pearl among them. I guess I can't explain this one, but I read this book under my covers with the lights on because was so afraid.
Who are your favorite/scariest villains? Sorry for the short post, guys. My forearms hurt, for some strange reason, and I hope it's not something serious, but I should probably lay off hardcore typing for a while.
