How vicious and brutal?

Well, let's do some comparison asking.

Was he more vicious and brutal than the current leader of Saudi Arabia, an unelected dictator whose people murdered and dismembered an innocent man in cold blood while he was visiting a Saudi embassy in a foreign country to get documents relating to his upcoming marriage?

Perhaps it's worth mentioning that that Saudi leader is a proud partner and ally of the U.S. government.

Was he more vicious and brutal than the leader of Egypt, an unelected military dictator who uses U.S.-supplied weaponry to kill, torture, or jail political dissidents and who suppresses the results of any election that doesn't please his military regime?
