Re: Why do religious people think they must prevent everyone from going to hell?
All of those civilizations had little or no Abrahamic influence. Being a Muslim, you would consider Roman religions to be false and man made anyway, hence, morality came from man.
Religion was the mechanism by which morals were delivered to, and accepted by, the average person. There is plenty of writing by ethics and justice by scholars who were non-religious, or believed in religions we would consider to be false. To think that empathy does not exist in humans or non-believers is absurd.
