the simple way is to observe who gets it, and build out a strong network consisting mainly of the righteous people, who are capable of recognizing wrong and defending against it. going into the crowd of wrong-thinkers and wrong-doers to preach righteousness is suicide... imho. let them destroy or weaken each other first.

There is no such thing as 'natural law'. It is a nonsense term.

Laws governing what is deemed to be acceptable and unacceptable human behaviour are human constructs, made and enforced by governments.
