You are better than killing off animals just because it attacked you. You release your hold on the wolf.
It looks up at you almost in disbelief that you would do such a thing. Letting a predator go free when you have the chance to execute it seems like a stupid decision to make. The wolf does not seem to growl or do anything aggressive once you let it go, it even licks your hand before it runs off into the woods. You think you just made a new friend.
You return to your camp, tired after dealing with him.
