1. "What is hateful to thee, do not unto thy fellow man: this is the whole Law; the rest is mere commentary." - Hillel the Elder
2. It is not necessary to believe in (or to be afraid of) a supernatural being in order to always follow #1 as a part of one's nature. It's does help to be raised by loving parents who very early teach about right and wrong. But I noticed that my 4 year old son already had a very powerful sense of morality, so I wonder if some of it is innate.
“It’s does help to be raised by loving parents who very early teach about right and wrong.”
Where are mom and dad learning right from wrong?
I think you’re right about innate morality. Personally I think God gives moral restraint to man. Revelations is essentially all about that moral restraint fading away and the necessity of judgement on the earth. Heavy stuff :)
