Look, Hitler was a fucking hero, to the Germans. There's no ultimate, single, universal scale of heroism. This isn't all being judged in God's eyes, and He isn't telling us who the heros are. Caesar was a hero, to the Romans, but not to the followers of Christ. That said, we owe more of the modern world to Caesar than we do to Christ. So we should render unto Caesar some credit for that.
There are some clear cowards in this story. It's cowards who spy and lie. God has personally identified these cowards to me. But heroism, by contrast, is always relative to point of view. Charles Manson was a hero. Justin Bieber is a hero. The congressman threatening to throw the reporter off the balcony was a hero. And everyone who is a terrorist to us is a hero to other people. Similarly, our heroic troups are terrorists when they enter civilian homes at night and kill the people there.
This doesn't mean there aren't "real" heros and terrorists. Just that the reality of both depends on who you are, and where you're looking at them from.
