Invented? Hmm...

...are you saying that all gods are invented including the Monotheists' god?

By the way this 'vengeance and revenge' is not terribly accurate , despite being re produces allover the internet/tv/games industry.

Nemesis in ancient greek mythology is the divine or not action that follows 'hybris' . Hybris is an act of arrogance, of self pride above someone's virtues, an act that insults the 'fair and the just' , an insult to something sacred.

When someone commits Hybris usually a God is insulted and Nemessis occurs to bring things back to order and correct the insult or injustice that happened. As a result the goddes Nemessis is not a goddess of revenge or vengeance but a goddess of order, restoring order and correcting the unfair and bringing someone who overestimated his virtues back to his rightfull place, to be more exact.

...Now claiming that the gods were 'invented' IS a hybris...very good case of Hybris...
