Again, it is usually a good idea to do what feels right. That is your moral compass. But when you are angry with someone, or dislike them, you enjoy hurting them. So, when you contemplate actions against them that hurt them, you will get a good feeling. That is not the good feeling of morality, however.

This website for the most part talked about the strategic advantages of being courteous and polite. Actually trying to like your opponent is a good way of accomplishing those goals. Now we see another strategic advantage to trying to like your opponent: It helps you to be moral.

There is a second problem with anger, though it is a smaller problem. It is my theory of anger that when you are angry, you tend to have no concerns for your own safety. (Perhaps others have espoused that idea, perhaps they have not, I don't know.) One signal that you are morally correct, discussed above, was that you are sacrificing your own concerns for doing what you think is right. Now we have to add that anger can mimic that signal.

If you are angry, and you want to hurt someone, and you decide on something to do, are you doing it because you are angry or because it is the morally correct thing to do? Ask yourself, will I like myself if I do this? Does this help me like myself, or make it more difficult for me to like myself?
