Confucius, and some Jewish Rabbis, taught a negative version that went "What you do not wish for yourself, do not do to others." What Christ did was take that and turn it into a positive "DO unto others as you would have them do unto you."
He went beyond justice, far beyond the "non-aggression principle" and made the standard for righteousness mercy.
You see a man who has been beaten and robbed and say "I am not gonna kick a man when he is down because I would not want to be kicked when I am down" then you have done the Confucian version of the "Golden Rule."

In the parable of the Good Samaritan, the callous travelers did not violate the Confucian Golden Rule, but they did the genuine one.
