Was Emperor Qin cruel or nice?

I believe that Emperor Qin was a very cruel ruler in that he forced everybody to do very hard labor like for his tomb and the great wall.  To build the Great Wall (long wall)  he forced over 300,000 soldiers, peasants, slaves, etc. to build in extreme weather conditions in mountains, deserts, quicksand filled jungles.  Many people died and were buried in the wall which is why it is called the longest graveyard in the world.  He also had people executed in extremely torturous ways including being pulled in four directions by chariots until you break into pieces or being chopped in half at the waist with a hatchet.  Another thing he did is that he would arrest or kill people for the slightest disrespect.  Overall Emporer Qin was very cruel.
