Wolves don't suffer things like guilt or remorse. They don't have any problems with the amount of discipline that they give to a fellow pack member, because in their world, the family is what matters, not the individual. So when you go in with a pack of wolves, you have to leave your emotions at the gate. When you come back out, it's very difficult to pick those emotions back up again.
