>>21530205Societies condemn rape and murder because this is universally bad for maintaining a society. Hence all the societies that allowed rape and murder collapsed already and even the human mind has been wired to be averse to this. This is interesting because it is universal and because of that it is probably a good choice for societal morals. But that only makes it morally 'optimal'. Objective morality isn't a thing unless you can show me 50mL of justice or 20 grams of love.
You are correct in your thinking about how morals and societal stability is related but you've gone too far and are saying things that aren't true.
