The great dilemma! If God does not exist then anything goes if you can get away with it. That is the bottom line. Many people already operate with this as a given. The glue that keeps civilization together is the all seeing, all knowing, all holding accountable, entity that we will be judged by and put into damnation by. if that entity does not exist many good people will lose their moral compass and we will all be in trouble. OH HELL! that has already happened it is called government.
