Ethical systems are judged according to different norms by different people. In particular, it’s common to say “System X has the consequence that doing Y is obligatory/good/bad/prohibited, which is obviously ridiculous” and use that as grounds for rejecting system X, and that sure looks like a moral norm to me.
Ethical systems a re judged right and wring by epistemic norms, not moral norms.
