God punishment isn't needed, just punishment is. It's simply that God-punishment is more difficult to challenge in the courts.

True but on the other hand, we're left with moral relativism as you yourself pointed out in your babyeaters parable. The only reasonable thing we can say about morals wrt to any posited God is that morals given by a God are an absolute guideline as defined by a "higher authority".

The systems of laws we have evolved as guidelines today in western countries are not bad in terms of maximization of benefits for most of the population, but they are subject to corruption by free-riders and those who seek to change the rules for their own benefit even if others lose.

Any case, good post.

Agreed
