Does religion have Monopoly on Morals?

...morality itself is a social construct developed by culture, not religion, religion is just an influencing factor in the shaping of moral views.

What religions do have is a monopoly on is Sin.

I partially agree and wholeheartedly agree with the first and second points entirely. The only problem is that, in the case of the former, a social construct is built on faith, as is the case in some islamic lands.

This is a rather heavy debate though. Once we were savages, then we became civilized. Just when was it deemed that killing another person for pleasure was bad? When did we grow out of being cavemen and became cosmopolitan humans? It's kinda hard to say I'd answer. Did religion have an impact on that? Of course, but I doubt it was the deciding factor in it's creation... maybe just a part of it.
