Whether animals have souls or not I don't know; I don't care, actually.

I don't think humans and animals are mutually exclusive terms. Humans are by fact animals, though we have morality and self-consciousness to set us apart.

And, for what it's worth, I can be very bestial and brutish at times. I need to be, at certain times; it's a social and evolutionary necessity.

Talk of "categorically evil" or "categorically good" tires me, and disappoints me. There's absolutely no contextual relativity taken into account at all with this condemnation of terrorists.
