5. Idi Amin
When a cannibal runs a country, atrocities committed by his regime are beyond any imagination. For Idi Amin had only oranges tastes better than human flesh. He is the most barbarous of all bloodthirsty dictators in the world and killed over 800,000 people. Nobody knows how many of them were eaten. Idi Amin was ousted by rebels in Uganda with Tanzanian army help and welcomed with open arms by Saudi Arabia, with whom have all kinds of business in the oil sector. He died in August 2003, in his villa from Jeddah.
