Maximization of combined outcomes required both parties to cooperate. Cooperation resulted in greater individual outcomes relative to outcomes resulting from mutual non-cooperation.

It is very hard to change our interests. And sometimes, apparently, they clash with morals and ethics. The solution is in attitude. We have to control our feelings. If we are led by negative feelings no matter how much we want to be ethical and moral, we can't. But if we have positive feelings, there is no need to think about moral and ethics. They will come naturally.
