Most of the moral dilemmas I face in real life I've never read about in ethics or philosophy classes. Most of my real world experiences are more along the lines of decision theory/prisoner's dilemmas.

So for example, if someone has wronged me, what does moral philosophy say I should do? I'm not sure because I don't really know where to look or even if this question has been answered; to my knowledge it's never been addressed in any philosophy or ethics undergrad courses I took.

But from a prisoner's dilemma point of view, I have to juggle whether I should cooperate (let it slide) or defect (retaliate). If I let it slide, then I might be sending the signal that I'm a cooperate bot and future agents will think they can take advantage of me. But if I retaliate, then this might descend into an infinite loop of defect bot behavior. And from either of those nodes, I have to take into account the degree to which I cooperate or defect.
