Obviously he would never kill human but if a wolf attacked him would he snap its neck or find another way? What if a little kid is walking a dog and the dog gets off the leash and tries to kill Batman, the whole time the kid is crying knowing what Batman may do to it, what would he do?
@theocitylegend: SAME. I'm just wondering. In an Arkham Unhinged comic I have it appears Batman snapped a Wolves neck, it was attacking him and Batman grabbed it by the neck. Next page it was laying on the ground.
Just close your eyes and pretend it didn't happen.
If the animal was hostile I think he'd do his best to avoid killing it and subdue it but you can't save everyone!
Batman does a pretty decent job of not killing anyone or anything currently, so it's not in his nature to use death as his first attack, though if it came down to the wire I think he'd kill an animal.
