Empathy altruism

Explanation:

Empathy altruism is a social exchange theory. In this theory, people help those people who experience the same situation as the person who supports the person have experienced the same feelings. When a person feels to help another person then the person supports that person. They help that person without any demand. And in another way, we can say that people help another person because they pleasure or happiness in helping others. When the people do not feel empathy then it transfers to the social exchange theory.
