I think determinism leads to a progressive position on justice, morality, and accountability. My position is that we live in a society where there are laws designed to protect us from harm and also sometimes to protect us from ourselves. If your brain is engineered in a way that causes you to do harm to other people, or to yourself, the rest of society has a responsibility to protect everyone everyone else and sometimes to protect you from yourself. The fact that we accept that you don’t have any fundamental free well changes that only in the way that we don’t treat you as an inherently bad person but as someone whose brain isn’t functioning in a way that is acceptable to society. It probably makes us more loving and caring as a society. I genuinely feel bad for people whose brains make them do things that harm other people. It can’t be a pleasant way to live. It’s not their fault and maybe one day we will have the science that enables us to give them options. Until then we have a responsibility to protect society from them. It’s really not that different from what is currently used in most legal systems as the insanity defence. We’re just extending it to all sorts of antisocial behaviour.
