Man's humanity to man

What if religion was inscrutably proven not to exist? Would mankind retain it's ethical behavior, or will malice form from the dark depth's of man's mind?

Best for the philosphy or religion forum.

You'll just get "bewbz" "ballz" and "lame" comments from the OTF.

Or none at all.

Meant to put this in the general discussion forum dammit, and i didn't feel it was a religious topic, but rather a introspection into man's own morality

the law?

Is it supposed to be inhumanity?

It would not turn out good.
