I think Eugine_Nier might be trying to say that the reason we evolved the emotions of anger and thirst for vengeance is because being known to be vengeful (even irrationally so) is itself a good deterrent. And possibly that this therefore makes these the same thing. But I’m not sure about that because that seems to me like a straightforward case of mixing up adaptation executors and fitness maximizers.
