What do you mean, you are heartless and I am unjust?

Hello, "You are unkind and I am unjust" is an idiom, which comes from the seventh time in Feng Menglong's History of the Eastern Zhou Dynasty in the Ming Dynasty: "He has no benevolence and I have no righteousness. The son will avoid disaster and do great things. " I'm in trouble now, and I need your help badly. Don't tell me about benevolence and morality. There are fifteen in the first grade, so don't blame me for being heartless when you need me in the future. When such words are spoken, they usually mean threats and retaliation.
