Very much, thank you. Your feedback has been a great help.

Given that others arrived at some of these conclusions before me, I can see why there would be disapproval -- though I can hardly feel disappointed to have independently discovered the same answers. I think I'll research the various models more thoroughly, refine my wording (I agree with you that using the term 'deontology' was a mistake), and eventually make a more complete and more sophisticated second attempt at morality as a decision theory problem.
