You would have to kill yourself then because the dog didn't get the rabbit killed.

It's not the dog's fault for doing what dogs do, it's the rabbit owner's fault for creating a situation where it could happen.
And the rabbit was in the dog's territory, not vice versa.
Somebody's pet gets loose and comes in my yard and one of my 3 dogs kills it, I'll feel bad for them but it's not my fault. If they do as you say and something happens to one of my dogs as a result, somebody had better be ready for war.
