Their moral views were quite different from ours. For example, they would have trouble viewing depictions of something as "bad"/moraly corrupting (the corruption would be in the mind always, not in the picture which is passive), so our concepts there would be quite alien (thinking about the Late Roman Republic). Similar for violence in some areas - much more opportunitistic there (not quite the right word, they were kind of hard-nosed pragmatists in a way).
