Human nature is simply to react, to give back with the same medicine that others gave them.
God imitates man. Go beyond your nature with others, and He will do the same with you.
This is what Rava, the Sage of the Babylonian Talmud, used to say: Ignore the impulse to return evil with evil, pain with pain, contempt with contempt - and the heavens will ignore all the disorder you have generated in the past.
