Interesting post Rex,
I have to think a bit deeper into this matter, but as first I want to comment on your assuption that universal moral laws exist...
I do not see why you can conclude that.
1) we are not looking at something universal we are looking only at 1 spiecies, the human spicies. We do not know of the existance of other species so we are unable to assume anything on them, especially their moral standards.
2) an example can be seen with animals, they do not have moral standars (or if you would cout the instincts, the moral standard are varying) why is that, if it is that universal?
3) our personal moral standards are not developed individual. There are developed with input of other individuals, so they are cultural determined. Making it very logical that moral standards of individuals look like each other, giving the impression that a there is a universal moral standard while there is maybe no such thing.
4) Is our mral standard also not developed by phisical realities. Like pain and our will to survive. These things have biological origins, and the projection of these origin to others is not more thenlogical, giving again the impression of a universal morality.
5) when we look at history, we can find very little traces of universal morality. Morality has been cultural influenced and is changing over time.
Even things like murder, have been defined very differntly. In some cultures it was quite normal to sacrifice persons (not enimies, but for example a princess). So if there is an universal morality, where is it?
