I agree there would be a large moral shift, and it kind of boggles my mind to try to think about it, but I don't think it's necessarily untenable.

Taking the candy bar example, in current society, even someone who doesn't believe in free will probably won't steal a candy bar, since there's a good chance they'll get caught, and then shamed and fined. There can still be a system of rules without a sense of free will.

The mindset would probably affect every aspect of life, but just looking at criminal justice, my intuition is that we would reduce how retributive it is, and switch to something more rehabilitation focused. Then again, it's hard to imagine what the knock on effects of that would be. I could see it going too far and getting exploited. Still, I'd be happy to see society experiment with moves that direction.
