Zhao Gao
There is a theory that Zhao Gao was a descendant of the royal family of the Zhao state, which was destroyed by the Qin state, and Zhao Gao was seeking revenge on Qin. With Zhao Gao in charge of the Qin government, it was natural that the Qin Empire collapsed in such a short time. In fact, Zhao Gao killed all the sons and daughters of Qin Shi Huang, including the Second Emperor, Huhai. In revenge, Ziying killed Zhao Gao and all of his family members. Thus, Zhao Gao or his brothers have no known descendants. Commentators who hold this view praise him for his part in the destruction of the Qin empire.
