The nature of a human being is to simply react, to throw back at others the medicine they mete out to you.

This is what Rava, the Babylonian Jewish sage, would advise: Ignore the urge to return bad with bad, hurt with hurt, scorn with scorn
—and the heavenly court will ignore your scorning, your hurting, your acts that were less than good.

G‑d shadows man. Go beyond your nature with others and He will do the same with you.
