Why do many people like to restrain others rather than themselves?

Restraining others but not themselves represents their ability and uniqueness in some people's minds.

Because China's ancient culture is too mean, as a rebound force, unique people are more desirable.

For example, emperors in feudal times. They will use all kinds of rules to bind the world, but they are unscrupulous.

It is precisely because of this precedent that many people would rather restrain others than themselves.
