[Batman] Where do zombies and other undead creatures fall under Barman's "no killing" rule?

Can batman kill a zombie because it's already dead?  What about a vampire (the mystical kind, not the viral kind)?

They are already dead. Generally, his no-killing rule only applies to living humans. Aliens and the undead, he has less qualms about.

Batman has had no moral trouble putting down vampires he's encountered, by the way. He's fought Dracula in several continuities (and put him down, hard, in most of them - in one continuity he actually *became* a vampire).
