What is the purpose of all of us laughing at others?

If you laugh at others, you must think this person is not good, but if you think others are not good, you must be good at it. If you are not good at yourself, you will not feel bad at others.

So the implication of laughing at others is to raise yourself and hint at how powerful others are.

But some people are not so good themselves, because they think others are ridiculous, so laughing at others, that is, laughing is a bad habit of people who laugh at others, and there is no intention of hurting people maliciously.
