The point about the philosophy professor contains a subtle and I think profound error. Even in a world of mindless automatons rewards and punishments still make sense. Your philosophy professor is "choosing" to change the inputs to your program to induce the correct behavior.

The same reasoning can apply to the debate over imprisonment, even if a rapist is only doing that because the neurons happened to fire a particular way, externally we can change (at least some of the time) those neurons firing if we precommit to a harsh penalty.

At the end of the day its very hard to distinguish arguments like "we shouldn't help this poor person because they could have used their free will to be not poor" and "we shouldn't help this poor person because that will change their mechanistic inputs and alter their behavior to be not poor". Obviously there is a social question of how possible it is to change your behavior in such a way, but whether free will exists doesn't seem very relevant to that question
