As a sidenote to my previous comment: I do wonder to what extent deontological concepts of "Acting With Honor" and "Just Vengeance" evolved in human societies as an effective approximation of a TDT, which encouraged both initial cooperation and punishment of defections by making societal members into the sort of being that would instinctively cooperate and punish those people with accurate enough models of themselves.

On the other hand, attitudes of vengeance towards non-intelligent beings (beings that can't model you) are seen as much more... insane. Captain Ahab is perceived as a more insane figure than the Count of Monte Cristo; though both are driven by vengeance, because the former seeks vengeance against a whale, not against people.

Though mind you, even against animals, vengeance is rather useful; because even animals can model humans to some extent. The wolves in The Jungle Book learned to "seven times never kill Man", after learning that to hurt one man, means many other men with guns coming to kill wolves in return.
