20. Emperor Hirohito
This Japanese emperor who ruled from 1926 to 1989 is in charge of committing many war crimes and murdering thousands of Chinese, Indonesians, Koreans, Filipinos and Indochinese. However, he will remain the “most famous” for the Rape of Nanking, where 300,000 were killed and around 200,000 women were sexually assaulted. Tragically, he was also the one to force husbands and fathers to rape their wives and daughters.
