Morality is based on selfish interest
❝❝I can make a case that our morality is based on selfish interest. It's the Ethic of Reciprocity. You don't do bad things to others because you don't want them to do bad things to you. You do good things to others because you want them to do good things to you. If they cross the line, you're not bound to tolerance and courtesy.❞❞
