How to deal with the attack of others saying "You deserve to be single"?

First of all, if you are a person with bad conduct or even bad behavior, you deserve to be single, because no one wants to be with such a person. One's moral integrity is at least the basic principle of being a man. Otherwise, you are not even human. Don't you deserve to be single? Then, self-righteous people also "deserve to be single." You are self-centered everywhere, only you are right, and it is difficult to accept other people's opinions. This will only keep others away from you. Then how can you find someone? "You deserve to be single" again.
