"Because am a human." Or at least he is now, and he doesn't know how to change back to his normal form, or if he'd want to. "Never was a wolf so can't be one now. Only human. But still can howl."

He grins because he's not gonna stop howling, or chewing on things. Somethings are just built into his nature.

"Feel things when you kill them? Why? They should have left when they were losing battle. Should not have started fights they could not finish. So now they are dead." It seems so simple to him anyway.
