Sisyphus was a selfish and evil king who has escaped death from the Greek gods several times, but that made the Greek gods even more mad, leading to one of the gods of death, Hades to force him to push a boulder up to a mountain for eternity, and despite all his pain he is happy because people imagine him to be happy,and for some reason he enjoyed it, in fact he did regret a single second of it. (One must imagine sisyphus happy)
