1, why should people have morality? First of all, they should be conscious of their own interests. In any case, in a society, doing good is better than doing evil, and being a good person is more respected than being a bad person. For the needs of their own interests, people generally follow the current moral norms. It is through the moral experience in society that people gradually realize the value and significance of morality and establish their own moral outlook. Morality with personal characteristics often conforms to the current moral trend and facilitates harmonious coexistence with others in social life.

2. Why should people have morality? Secondly, it is based on tradition and law. Traditions and laws established for a long time dominate people's behavior to some extent. These traditions and laws inspire people to have morality, and those immoral people are often criticized by tradition and even punished by law. This kind of positive and negative moral stimulation forms or corrects people's moral understanding, and then becomes the inheritor of tradition and law.

3. Why should people have morality is actually the same need of people. According to life experience and common sense, we can easily find that people have many similar needs, desires and purposes. For example, we all want to live in harmony and have a harmonious family. We pursue freedom and happiness, and we are happy to enjoy love, friendship and affection. In order to meet these needs, we must establish and abide by some moral principles (bottom line), so that we can be free from fear and loneliness, from being deceived, controlled and mutilated.

In the final analysis, we learn to live ethically in order to improve the quality of life and that of people around us. What could be more meaningful than this? As Einstein said: "The most valuable effort of mankind is to strive for the moralization of our behavior. Our inner balance, even our existence itself, depends on morality. Only the moralization of our behavior can give life beauty and dignity. "
