iirc aren't wolves actually quite solidaric? Where if a prey shows themselves capable to hurt the pack, they will abort on behalf of retaining the integrity of the pack, as opposed to selfish desire for food at any cost using wave-tactics. And if there's a predator that shows itself capable and wanting to hurt the pack, they gang up to take revenge to ensure it doesn't continue until the pack has been whittled to extinction. Even if that means additionally sacrificing their own life to ensure the kill. It is also why a starving pack is so much more dangerous, as they will start punching up when hunting and no longer abort just because they risk losing a member or two.
Standard social pack-animal behaviour, even seen in humans. It is why we have those stupid lizard-brain things that makes it possible to induce us to throw our lives away in war for "the homeland", or other such situations (some gunman threatens your family? Lizard-brain might kick in and have you sac your own life to disarm or kill them).
