Its the natural law. Murder,rape,stealing-bad. It is what a republics law is based on. These things are universally identified as wrong and the reason all societies penalize them. We know there has to be an absolute right and therefore an absolute wrong otherwise we could not measure anything. There must be absolute beauty in order to know ugly, there must be a moral code to know sin. People “tweaking” codes is why there is so much strife and division in areas like social justice, abortion, marriage, etc...
Perhaps some people have a different natural law designed into them? I agree that you and I and most others believe they are universally wrong, but that really doesn’t deter people does it? Maybe they believe differently? Not everyone measures things the same, do they? People have been doing this tweaking since there have been people and we have had these problems for just as long. Perhaps, there are some people born good, and some born bad?
