Well, you see, Willard, in this war, things get confused out there. Power, ideals, the old morality, and practical military necessity. But out there with these natives, it must be a temptation to be God. Because there’s a conflict in every human heart, between the rational and irrational, between good and evil. And good does not always triumph. Sometimes, the dark side overcomes what Lincoln called the better angels of our nature.
~ General Corman
