It's not that I think the phrase is useless; it has many uses.

It's that I think we use it to mean such different things I think this conversation is not well-served by introducing it. (You use it to refer to judgments related to weoc, I use it to refer to judgments related to the judger's values.)

Yes, I would say that sociopaths make moral judgments, although their moral judgments differ from mine. I realize you would not say this, not because we disagree about sociopaths, but because we disagree about whether what sociopaths make can properly be labelled "moral judgment".

I don't think the labeling question is terribly important or interesting. As you say, "moral" can usefully be cashed out in other terms.
