Right, man is inherently evil...we must fight everyday to be "good". My personal view would moderate that somewhat: Man is flawed, with both the possibility of good and evil. Religion, civilization, logic, ethics, and morals can encourage more good, and help disuade evil. I agree that it is a personal daily fight to bring out the good and suppress the evil.
I just hold that it is a whole lot easier for a man to do evil than it is to do good. All the things you listed help disuade a man from doing evil...if it weren't for those things we would still be clubbing each other over the head and takiing what we want.
