Wolves are irrelevant here. If we're talking about the morality of the way we treat animals, it's a logical fallacy to try to use wolf behavior to justify our own (and something I'm sure would never occur in any other discussion of morality).

Human society tends to operate on that logical fallacy. The badness/awfulness of others is taken to justify "extreme measures" from our own side. (And I would agree that this is wrong.)
