It depends. Do you regard your enemy as a good person doing a bad thing, or as a bad person doing a bad thing? If it's the former then teach them a better way a la MLK and Gandhi. If it's the latter, then teach them a better way a la Malcom X.

If you can see some compassion or love in your enemy's eyes, then every time they hold up their fist to beat you you should hold up a mirror.
