It's not that, um, we can't kill humans it's just that wild rogue killing isn't allowed. We're predators... Violence is kinda in our being unless you're a submissive. But submissive wolves are kinda rare. But mostly the humans that die are the ones that deserve it or are too stupid to walk away when they should.

You're not, like, the Lucifer are you? [Unfortunately, she can't see that he's an elf and not, say, a demon.] Fire, brimstone, Lord of Hell and all that church stuff...
