Ethics
From Iron Chariots Wiki
Ethics (from an Ancient Greek word for custom) is one of the major branches of modern philosophy. It concerns the nature and origin of moral behavior, and concepts such as "right" and "wrong", goodness and justice, etc. The word ethical means good or morally acceptable.

Religious people who see morality as being determined by God's will like to denigrate situational ethics.
