There's a darkness inside all of us; a darkness just waiting to get out. Well, maybe not so dark that we'd go around killing people. Still, we get an odd pleasure from tapping into our devilish side (it's healthy, right?

Are you a puzzle-loving punisher like Jigsaw, or a quick-witted cannibal like Hannibal Lecter? Take the quiz to find out. (Want more stuff like this?Like us on Facebook.)
