He doesn't feel it right, so it's bizarre... Instead of feeling guilty about the blood he has shed, he feels guilt over not shedding it sooner! It's a little sad, since he seems to think things would have turned out better for himself and his sister otherwise... [which he says in the same flippant way a person might chat about what they had for breakfast, complete with a dismissive wave. he sure doesn't care as long as he gets to keep the body.]

What about yours? I'm curious.
