Setting aside the obvious questions about how wild vs farmed animals are raised, wolves don't have a choice about what to eat, while humans do. Even if we wanted to improve the status of wild animals, murdering wolves isn't obviously the best way.
So what if they don't have choice? If a mentally deranged person commits a crime because they didn't have a choice, we still remove them from doing further harm from others. Would you not kill a wolf attacking a person? If we are saying that animals are equal, then we should also be protecting the innocent prey.
