It's the consequences of our actions...Here and now...In this world, and to this human life that determine whether an action is right or wrong. Any action leading to the harm of one's self, to others or to both is not to be undertaken. Unfortunately, we're mostly of the mind that so long as it doesn't hurt me, everyone else can go to hell. And that attitude is the road to hell on earth. We don't need the threat of a hell or the promise of a heaven to be good and moral people. We simply need to understand that in order to live a good life we must make this life in this world the measure against which the consequences of our morals and values are weighed. If it is hamful...It is to be discarded. We don't need to worry about all of the metaphysical claptrap surrounding the idea of rewards and punishments in some mythical afterlife. Understand the consequences of our actions here and now, and there is no need to worry about an afterlife...It'll sort itself out.
