Here is a different question - what makes it an atrocity? You could be technically correct and say "Because other people decided it." but that doesn't give any insight into why.

A natural rights framework has the thumbprint of a lawyer along with outmodedly telological way of thinking that can only see a wrong as a "crime" but is willing to construct justifications for what they already believe.

But mixed in the principles isn't just accepting "is wrong because I said so" as a proof. Thus it has contrived post hoc cruft to achieve consistency with assumptions but also underlying ethical principles.
