Welcome, Judaism
“What is hateful to you, do not do to your neighbour. That is the whole Torah; the rest is commentary.”
— Hillel the Elder, Talmud, Shabbat 31a
Hillel stated the passive Golden Rule two thousand years ago and called it the whole of the Torah. The Ultimate Law agrees: this one principle, combined with logic, is sufficient. Everything else is explanation. Judaism understood this before anyone wrote it down as law.
The Ultimate Law
Logic is the ultimate law.
Do not do to others what they would not want to be done to them, or you will be punished regardless of your will.
The purpose of punishment is to erase guilt, via retribution and restitution.
That is the entire law; it cannot be changed, all the rest is commentary.
