Within the limits of your statement , Yes. However below the societal level there is a species set of norms involving reproduction, food, possessiveness aggression and other things we call instincts. They give us all a common starting point on the map from which to proceed. For instance. Some other species eat their own young. No one of us do.
Instincts are genetic. Like the instinct to eat. They need to be bred out, they can however be overwritten by social convention. Remember the last time someone Teed you off and you didn't brain him?
yes I agree with that.!
I don't think any one society holds everything that should be instilled in one's life.!
