 So what will typical advocates of the morality system have to say to me afterwards about my dreadful sense of  regret?[16]  If they are—as perhaps they had better not be—totally consistent and totally honest with me, what they will have to say is simply “Don’t give it a second thought; you did what morality required, so your deep anguish about it is irrational.” And that, surely, cannot be the right thing for anyone to say. My anguish is not irrational but entirely justified. Moreover, it is justified simply as an ex post facto response to what I did: it does not for instance depend for its propriety upon the suggestion—a characteristic one, for many modern moral theorists—that there is prospective value for the future in my being the kind of person who will have such reactions.
