Having morality, laws, and justice systems is an evolved trait of racial groups that build advanced civilizations such as Europe, China, and Japan. Religion of some sort tends to emerge out of these societies as a way of further enforcing this morality that allowed them to get ahead.
A society which relies too much on murder and rape (i.e. Africa) can never industrialize and expand when they are too focused on beating each other up with sticks and stones.
