 It gets out of hand, and the question of ethics and morality always seems to come into play, don't you think? Oh, of course it does. And I think that the most profound lesson that I try to get my students to recognize and that they hear from, again, these combat veterans that I bring in to speak to them is that you can't put your morality in the hands of your enemy. And what I mean by that is you can't control what they're going to do. You can't control what their values are.
