18. Idi Amin Dada
Idi Amin Dada ruled Uganda for only eight years, yet he made sure that he left his mark, albeit one that puts him in bad light. He was known for his brutality and earned the nickname “Butcher of Uganda”, claiming the lives of about half a million people through extrajudicial killings and genocide. He sent out killer squads to take down his opponent’s supporters.
