RE: "...religious believe they some how have the monopoly on benevolence...".
-Not so-they believe God has that monopoly, - man's benevolence, ethics,& even love are arbitrary & capricious. Morals didn't evolve, nor develop, they were revealed. Where does the conscience [which everyone has] come from? It didn't evolve-it was put in every human heart-it is not a coincidence that animals don't have one. Note that constant ignoring or violating one's conscience will sear it, & restoration is difficult like overcoming an addiction.
