If all 'moral worth' meant was the consequences of what happened, I just wouldn't deem 'moral worth' to be that relevant towards judging. It would seem to me like we're just making 'moral worth' into something kind of irrelevant except from a completely pragmatic point.

Not sure if saying 'making the best decision you could is al you can do' is that much of a shortcut. I mean, I would imagine that a lot of smart people would realize that 'making the best decision you can' is still really, really difficult. If you act as your only judge (not just all of you, but only you at any given moment), then you may have less motivation; however, it would seem strange to me if 'fear of being judged' is the one thing that keeps us moral, even if it happens to become apparent that judging is technically impossible.
