We are definitely not our brother's keepers. Hitler knew about the Armenian genocide and knew that the world took in stride this genocide. He rightfully assumed that the destruction of the Jewry, done in relative secrecy, will not elicit any response. We will punish the perpetrators later. Later a dozen of perpetrators were hanged and in the meantime millions perished.
Violence sponsored by a state is considered a patriotic duty.
The basic function of civilization is curbing of the instinctual drives by developing a conscience, superego as defined by Freud, morality, integrity, ethics, or whatever on call it. It is possible to create a culture in which religion can safeguard Law and Order. We trained our courage, not with a view of waging war for self-aggrandizement, but in order to preserve our laws. To defeat in any other form we patiently submit, but when pressure is put upon us to alter our statutes, then we deliberately fight, even against tremendous odds, and hold out under reverses to the last extremity. It means that it is possible to have a society in which Law and Order is safeguarded by religion.
