The book begins this way. If you are asked who is the most evil man who ever lived, you might immediately nominate Hitler, Stalin, Genghis Khan, and Mao Tse-Tung, all of whom easily exceed double figures in the numbers of their murder victims, and to round out the top five you could throw in Leopold II of Belgium although he won't reach the finals. May I have the envelope please? The winner is: None Of The Above. The most evil man who ever lived is Muhammad. That is my opinion and I shall endeavor to back it up with facts.
