The perception of good and evil in war is subjective and depends on the cultural and historical context. While some behaviors are widely considered evil, such as the Holocaust or the medical experiments conducted by the Japanese in Manchuria, the perception of what is good or evil may vary depending on the perspective of those involved in the conflict.
The Second World War saw more civilian deaths, which complicates the good vs. evil narrative of the war since both sides have different views and interpretations of what constitutes good or evil.
The perception of good and evil in history is subjective and shaped through a lens of one's belief system. While acts such as Unit 731 in Japan during World War II are perceived as evil by Western standards, defenders of those actions argue that the Western liberal democracies are not exempt from committing atrocities like strategic bombing.
