He was the architect of the French Revolution. As a younger leader, he advocated better life for the people of France. But soon, his obsession with guillotining (beheading using a machine with a huge knife blade at the end) began. His reign of terror has been a famous part of history, he killed over 40,000 people within 10 months and believed that killing was always better than forgiving. He ordered an attack on Vendée, killing over 100,000 men. Ironically for him, Robespierre was also guillotined without trial.

3. Pol Pot (1925-1998)

Pol Pot was the leader of the Cambodian revolutionary group the Khmer Rogue, which had orchestrated the Cambodian genocide. Pol Pot believed in destroying the Cambodian civilisation in order to start a new regime and usher in a new age. He is probably the only man is history who ordered mass genocide on his own country. During his reign as Prime Minister from 1976 to 1979, his policies led to the death of around 2 million people which was 25% of the entire population. He liked to keep the skulls of people he had killed and he went as far as ordering babies to be torn limb by limb. He died of natural causes.
