8. God of War (series)
After five God of War, I think it's safe to conclude that Kratos is not a very nice guy. Sure, the vast majority of the Spartan's bloodcount consists of mythological monsters who have it coming, but he's shown time and time again that he's not afraid to kill the occasional human or god who gets in his way. This means a whole lot of bloodshed and, more importantly for our list, a whole lot of quick-time-event decapitations.
Kratos may be the hero of the series, but his behavior in the God of War games—especially the third one—is far from heroic. At one point, he shoves a woman into a gear, jamming the mechanism and killing her in the process.
