[Evans, Marv]

I would imagine people in the past were less moral in terms of our judgement. They used a lot of institutions to cover up/ justify perverse behavior (the Inquisition, witch buning, etc. - of course I think things still happen along those lines whenever there is a fairly closed, authoritarian enviroment - Warren Jeffs comes to mind). The lack of enforcement of rules because of a sparse population spread out over wide distances probably contributed to lots of things like unlawful behavior, incest, etc., etc. I think lots of people now would act less moral under those circumstances.
