The first thing to note about the impact of the divine on morality is that it's completely impotent when it comes to choosing which moral decisions are right, and which are wrong. The only advice it offers is recorded in a plethora of readers digest sized stories with consistently conflicting messages. And the only way to extract any guidelines of morality from these is to choose which stories have a literal message - and therefore should be followed - and which ones should be interpreted allegorically (i.e. taken as fun little ditties about genocide and such).
However, presumably you will just pick the ones that you consider to be morally satisfying, proving you already have the capability of navigating the moral minefield yourself and rendering the whole laborious task as redundant in the process.
But wait, maybe the fact that an omnipresent all seeing eye will record your every move throughout your lifetime and pass judgement on whether you should be left alone or tortured for eternity, will force you to behave consistently more inline with your own set of morals. No. I don't think so. For as anyone who has ever tried to develop themselves or change a behaviour knows, it's so much easier to do as expected - or conversely it's a huge advantage when trying to turn over a new leaf if nobody remembered how you were before, or even better, nobody saw it in the first place. The ever watchful eyes of people around us will seduce and coerce us indefatigably into acting just the way we always have.
And if you've ever heard the expression 'in for a penny in for a pound' - most commonly used when breaking a diet - you will know that building artificial levees to contain a behaviour that you have a compulsive inclination towards, will succeed only in postponing the eventual flood until such a time when the pressure is so great that it can no longer be contained and pours out in an uncontrollable frenzy.
Or to put it into the terms of religious morality: denying your homosexuality until the ever mounting pressure finally causes you to sell all of your belongings and embark on a round the world safari of carnivals, gay bars and public toilets…
