This is the total lack of moral judgement, or as the watchtower calls it "a bible trained conscience".
One of the best definitions of JW morality I've ever seen. Jws are morally disabled. Almost every moral aspect of their lives is predefined in thousands of detailed rules published by WTS. They're only left with a few petty choices which give them the impression of moral freedom. Life is easy when someone else does the thinking for you. But as you rightly point out when you lose your own morality, you are immoral, no matter what you replace it with.
