In ancient Greece, hubris (ancient Greek ὕβρις) referred to actions that shamed and humiliated the hero or heroine of the story for the pleasure or gratification of the abuser.
Ate, ancient Greek for "ruin, folly, delusion," is the action performed by the hero or heroine, usually because of his or her hubris, or great pride, that leads to his or her death or down-fall.
In the Greek tragedies Nemesis appears chiefly as the avenger of crime and the punisher of hubris, and as such is akin to Ate.
