I was asked by a reader, in essence: Why bother being kind if the world is headed for destruction anyway?
I believe that we increase humanity’s chances for survival by being kind. When I’m kind, I feel good, the person I’m kind to feels good, and those witnessing the kindness feel good. I don’t see a down-side to making the effort. Even if the world is headed for destruction in the long-run, the world–and my life–will have been made better by acts of kindness in the meantime.
