The difference between good and bad is not so self-evident, it has taken thousands of years of work by generation after generation of civilized humans operating within civilization frameworks to develop. That’s even if one discounts the impact of the giving of the Laws to Moses and the Israelites.
The most cherished and perishable of legacies passed from one generation to the next are the moral laws, the rules of good and bad as established after the work of hundreds of generations.
It is in utter ruination that we allow the empty “morality” of relativism and the anti-G-dly “morality” of secularism to become our legacy to our children. It is empty, it will leave them with nothing but chaos, ruin and despair.
And we see it happening already, the current generation lacks any true moral rudder — instead the most evil steer these young sheep straight to the slaughtering pens.
