9Dexter from Dexter
Dexter is a serial killer who really savors killing people. Being alone in a dark alley with Dexter wouldn't be so great depending on his mood. Being alone in a dark alley with Dexter during a zombie apocalypse would be lucky. Dexter is a killer who seeks redemption, trying only
to murder serial killers and bad people. Well, zombies are pretty bad people. Dexter could work out all his psycho-killer tendencies by slaying zombie after zombie instead of killing you, and that makes him a great apocalypse partner.
