Whenever WoW reaches its final expansion against Sargeras (don't think he's actually been in a game yet) I gotta imagine he'll top this list, but his underling Kil'Jaedan must be in the running here, both directly and indirectly as the primary strategist of the burning legion.
Still, there's no doubt in my mind that while they may have the most blood on their hands, Mario certainly has the bloodiest feet :p
