So far our focus is focused on Anglophone soldiers that generally hail from similiar cultures. After a few hours of reading today about Japanese soldiers during the early days of WWII it is clear that they not only didn't hesitate to kill, but relished in torturing innocents and participating in mass rape long after the excitement of any combat. The German SS were also capable of visiting exceptional cruelity, as a number of others throughout history. As Anglophones we do surprisingly well at killing considering the values accepted as norms in our society, but there are others in the world who seem to be completely unhindered by what we would consider moral norms.

What enabled the Germans and especially the Japanese to participate in mass murder and torture? Their culture? Lower level of social development? Superior social development? Is it undefinable? When did we become relatively moral compared to our enemies? Was there a turning point in history?
