To sum it up, basically:
"If we considered factors in the individuals life, such as parents, experiences good and traumatic, and then choose what we felt was a good moral status, (lets say in this case one that is beneficial to others), could we not develop a logical, quantitative means of measuring morals?"
We could try, but what we would be measuring with that method wouldn't be the "goodness" of morals. It would be a quotient of the "goodness"/unlikelihood.
My personal philosophy though would deem the acquirement of the morality negligible (compared to the magnitude of "goodness" the morality has itself), and possibly irrelevant (because moralities can be archived in books and computers, and aren't necessarily attached to any person).
(I have used inverted commas sometimes when referring to "goodness" in these recent messages, because "goodness" is subjective. When I use the term "goodness" in these messages, I mean so with the condition: "If goodness was objective".)
