Did the Empire consider the Jedi evil? Have you considered the horror of the recent killings in Paris and California? In Peter Haas’ book, "Morality after Auschwitz," he noted,

....far from being contemptuous of ethics, the perpetrators acted in strict conformity with an ethic which held that, however difficult and unpleasant the task might have been, mass extermination of the Jews and Gypsies was entirely justified. . . . the Holocaust as a sustained effort was possible only because a new ethic was in place that did not define the arrest and deportation of Jews as wrong and in fact defined it as ethically tolerable and ever good.

Haas’s point is that the Nazis were not moral relativists or nihilists, but rather objectivists who had a different value system than those of us who see all persons as intrinsically valuable. Something similar could be said of Islamic terrorists today.

Without a God, there is no such thing as objective evil or good—that is, good or evil apart from what any of us believe about it. That's a scary world.
