I guess what I want to emphasise is that I don't think the reaction is illicit or even particularly subjective. One of the ways a system of ethics can fail is that it's impoverished. It doesn't capture everything we want to say about the subject. When you encounter a person or group who are living their life according to a particular ethical system and you have the sense of things spiralling away from normalcy, that's a legitimate cause for concern. It's a sense that something might be missing here. That's why I said it could almost serve as a reductio. It's similar to performing a long calculation and being left with the sense that the answer is an order of magnitude out.
