I too, have a kill list, but it is predicated on time travel, so I probably don't fit the description of a common tyrant. I would use time travel to go back and kill the following people at birth, or at least before they became powerful enough to defeat me. Using advanced technology, I would locate them in time and space, and dispatch them with weapons not available in their time:
- Mohammed - dictator, tyrant, warrior, pedophile, false prophet. Invented a religion as a form of crowd control. He and his religion are responsible for much death and destruction since its inception.
- Vladimir Lenin - political theorist, revolutionary, tyrant, dictator, communist, father of the USSR. He and his ideology and regime are responsible for much death and destruction since its inception.
- Josef Stalin - politician, dictator, bureaucrat, communist, successor of Lenin as premier of the USSR. He and his ideology and regime are responsible for 20,000,000 deaths since its inception.
- Adolph Hitler - politician, dictator, tyrant, national socialist (Nazi), fuhrer of Nazi Germany. He and his ideology are responsible for much death and destruction during World War II. His regime killed 6,000,000 Jews. But WWII claimed approximately 66,000,000 lives. Hitler was responsible.
- Mao tse Tung - politician, dictator, tyrant, communist, premier of Communist China. He and his ideology and regime are responsible for 40,000,000 deaths since its inception.
- Pol Pot - terrorist, dictator, tyrant, communist, leader of Kmer Rouge in Cambodia. He and his ideology are responsible for approximately 1,650,000 deaths during his reign of terror from 1975 ~ 1978.
- Karl Marx - political theorist, invented communism (and communist lite -- socialism), he and his ideology is responsible for much death and destruction since its inception (61,650,000 deaths, if you add up the deaths from all major communist regimes -- double that if you include Hitler's "contribution"). Also responsible for much pain and suffering in this country from around 1913 to the present time, due to the perversion of our constitutional government by his socialist followers in the US.
