Well, a "great leader" can be a terrible human being.We can differ on who we consider "Great Leaders", certainly.
Ghengis Khan was one of the greatest leaders in all of history, any list that doesn't include him can be dismissed as utterly ridiculous. He was not a very nice person.
Alexander the great was such a great leader that thousands of years after his death he is still called "the great". He also did some very unscrupulous things.
