He Who Repeatedly Commits Wrongdoing Will Come to No Good End.
A person who repeatedly acts immorally will only end up in total failure. Buyi (不义) is an act which violates the principles of yi (义 righteousness). Righteousness is the moral code broadly accepted by a society; it is synonymous with yi (宜propriety), meaning the observance of what is fit and proper. The Chinese have championed righteousness since ancient times, believing that all acts, whether those of individuals or of a nation, should be based on righteousness. Anyone who breaks laws, harms the country or the people, or commits numerous acts of wrongdoing will come to no good end.
He who repeatedly commits wrongdoing will come to no good end. You just wait and see! (Zuo’s Commentary on The Spring and Autumn Annals)
