Morality is the cornerstone of how people treat people they know, and ethics is the cornerstone of how we treat people we don't know. Therefore, it is morality that teaches people how to be good parents, good friends and good neighbors. Ethics is the cornerstone of human social construction and a real test of human inner good and evil. However, when the society is ruled by your personal morality and your family's personal morality, you impose your own morality on complete strangers. As a result, our society will become a society ruled by self-expanding individuals. For example, the personal will of the leader, Hitler-style characters. Those who are used to influencing and ruling the people around them with their own moral values sometimes do so in order to gain a sense of self-satisfaction, in addition to personal goals. He is proud of his unique morality, and at the same time he tries to influence others. In fact, he personally knows almost nothing about things, or deliberately distorts them for some purpose. At this time, such people have successfully contributed to the corrosion of the whole social structure by that force. And the people who echo, in addition to having no brains, sometimes protect themselves and don't want to be marginalized by the group. Personally, this is the essence of common social attacks and cyber violence.
