I’m not sure I’ve got this right, but the distinction I had in mind between plan A and plan B was not so much that one dealt with Israel’s sinfulness and the other didn’t. Deuteronomy 28:1-14 describes a way of obedience and blessing (without actually mentioning the sacrificial system); verses 15-68 describe the outcome of disobedience and unfaithfulness in terms of extreme affliction. If Israel had been obedient, then presumably the “curses” would never have come into force. What plan B does is find a way forward towards restoration and life through the experience of judgment, suffering and destruction. I totally agree that this entailed the liberation of the self and of the community from idolatry.
