Does good come from god?

It is my personal belief that actions become evil when they involve violating or taking away rights from another human being. I believe you can be as cruel to yourself as you want but when you are cruel to another person it becomes morally wrong. I did not learn this by reading any religious writing, but by my own human experience and interactions. Like all animals we strive to survive and succeed in our society. There will always be animals that step on each other to reach the top, and animals that are satisfied in the middle, and animals that push others to the top expecting nothing in return. We are but a complicated species with billions of personality trait combinations that effect the way we treat ourselves and the people around us. Religion is a good guide for most, but not needed for all humankind to live a compassionate life. Some already have it in them, and some will never have it.
