Abstract
Ender's tortured conscience is an illustration of the moral importance of following principles of just war theory—the “unspoken rules of manly warfare”—and their apparent tension with the demands of war and survival. This chapter talks about the ethics of conflict in Ender's various games—his battles and wars. It asks, was justice served in the Third Invasion and destruction of the bugger worlds, the event that came to be called the xenocide. Ender's life is actually a testimony to the just war axiom that all people desire peace. In the tradition of just war theory, there are five principles that lay out the requirements of jus ad bellum, or how to go to war in an ethical way. They include just cause, legitimate authority, right intention, probability of success, and last resort. Ender's strategy is always to use devastating force to incapacitate the enemy.
