The Nazis , during World War II , considered genocide to be acceptable , as did the Hutu Interahamwe in the Rwandan genocide . One might point out , though , that the actual perpetrators of those atrocities probably avoided calling their actions genocide , since the objective meaning of any act accurately described by that word is to wrongfully kill a selected group of people , which is an action that at least their victims will understand to be evil . Universalists consider evil independent of culture , and wholly related to acts or intents . Thus , while the ideological leaders of Nazism and the Hutu Interhamwe accepted ( and considered it moral ) to commit genocide , the belief in genocide as '' fundamentally '' or '' universally '' evil holds that those who instigated this genocide are actually evil . Hitler considered it a moral duty to destroy Jews because he saw them as the root of all of Germany 's ills and the violence associated with communism . Osama bin Laden found it moral to kill all Christians and Jews because he saw Islam as under attack by Western and US influence , accusing the US and Israel of forming a Crusader-Zionist alliance to destroy Islam , and considering US troops in Saudi Arabia infidels in the land of Islam 's two holiest sites . He therefore considered non-Muslims and Shiite Muslims evil people intent on destroying Islamic purity and therefore heretic
