The solution for infinite iterated prisoners dilemma given in the opening post is an example of potential bad consequences for punishing anti-social defecting behavior. A single defection at any point in the infinitely long game causes both players to get the worst outcome in the limit.
If both players are perfectly rational and error-free then this is not fatal. However, a better strategy with reduced punishment and some mercy gets better outcomes in scenarios where those assumptions don’t hold.

I agree, that’s a way better example because that type of punishment sounds like a potentially good strategy on the face of it.
