Abstract
Given the portion of his life spent at military schools, it is striking that Ender and his peers apparently never study military ethics. The ethical lessons Ender and his peers might have learned are so obviously relevant to operations against the buggers that you cannot help but ask how the I.F.'s leadership could have failed to teach military ethics at all. This chapter presents some highlights of Western thinking on the ethics of war and analyzes Ender's education and actions in light of those moral traditions. Ender's Game teaches powerful lessons for students of just war theory and the just war tradition because it asks questions that matter to everyone, from national decision‐makers all the way down to individual soldiers. Genocide and xenocide are extreme in their quantity of killing, but not necessarily in their moral magnitude.
