This is being down voted b/c the Nanking massacre is both old, and not unique. But ... it is worth examining the assumed strong culture of morality. Is it morality? Is it just norm-compliance or rule following? Is it shame or fear of shame? Is there really a basis for calling whole societies more or less moral? Or does morality just get expressed in different ways in different social contexts? Without invoking war crimes, one could ask about gender inequality, LGBT rights, or the status of racial minorites in Japan. Are these reflective of a particularly "strong culture of morality"?
