More like "without mercy" - humans mostly seem to have things like that, but there are definitely some without.

[He has to think about that second one, though.]

Those from the Underground...well, we don't really have physical bodies normally. Our souls are pretty much everything - once our soul is gone, there's nothing else left, we don't even leave bodies. And it's mostly believed that our souls are made of love and compassion, something like that. So I'd...assume so?

I don't know how much I agree with that; we can be just as bloodthirsty as anyone else, I think. I've seen a lot of that, anyway.
