1. Joseph Stalin
The beginning of his “career” was not bright since he started as a bank robber and later became a leader of the Soviet Union, remaining in that position for more than 30 years. It has been estimated that he killed 20 to 60 million of people, and his rule was known as one of the cruelest, since he was famous for torturing, raping and mercilessly killing, even those people who were his close allies. These and many other reasons brought Stalin to the first place of the list of 30 most evil people in history.
