The answer is: Those he/she has opressed. A tyrant will always looking over his/her shoulder to be ready for any counter attack from those he/she has opressed. Every shadow,every sound,every movement around him/her is another possibility of being attacked.
For tyrant all over the world, enjoy this, untill the day you die or correct things up,make amences. Which ever comes first.
