Earlier quoted context omitted.
If you refuse to engage with a challenging concept and instead talk about something else entirely, you make things easier. Go figure. Strategy helps us decide which actions will help us reach a goal. It does not tell us what that goal should be. It has practically nothing to do with morality. Human societies adopt different means but they also work towards different ends.
The only goal is self-preservation. It's universal. All individual "moral" decisions are based on this one goal.
It can't be disputed that morality is partly instinctive. There are those who argue persuasively that morality is largely self-deception, with our alleged values being just a way of rationalizing our instincts. I think you have something of a point. Still, your simplistic version is just plain wrong.
