The perfect moral code
This is indeed a tragedy, because the moral code around which the European nations and their descendants built themselves was, and still is, the best one that humanity has ever been given.
Note - I wrote, "given", not "devised". And that is because the moral code by which the most successful nations on Earth governed themselves, did not come from the mind of any one man of singular virtue and wisdom, or even a group of highly moral men.
That code came from the Almighty Himself. We know of it as the Ten Commandments.
The Decalogue is simplicity itself. No more than the Ten are required - but not one of the Ten can be disposed of without terrible consequences.
