How to treat people who always laugh at others?

These people are full of jealousy. They are jealous of everything. But I still like comparing with others. The result is that I am inferior to others everywhere, and jealousy may turn into jealousy. Keep hitting others with such offensive words, trying to give others less points and consume others' energy, so as to prove to yourself that you are not so bad, and it is best to lower others to the same level or lower than yourself. Most of these people have no goals, no serious things to do, and no efforts for anything. Their time and energy are spent on how to attack others, and they are full of tricks. It is essential to speak ill of others behind their backs and belittle rumors. It also has its specialties, such as yin and yang division, innuendo and so on. These people are often genial or arrogant, even "good-natured" and love to talk, and aggression is always indispensable in their words.
