Or look at it this way: if the universe is fully deterministic and we have no free will then what's the problem if a criminal goes to jail? It's not as if it means anything, and it was all pre-determined, no?
But the real answer is that we neither know for sure whether the future has been pre-determined, nor could we predict the future if it were, and we do not know if we have anything like free will, but we at least have the illusion of free will, so we have no choice but to act as if we do.
Rules can change, get better or worse and effect society in a little way. I have no problem with that! I’m not saying if someone cannot follow a rule it’s not good.
I’m saying the consequences of breaking a rule need to be a rehabilitation modal compared to a punishment modal. The illusion of free will is similar to humans once perceiving the world is flat. I’m a firm believer that it’s better to not live a life under an illusion and when the consequences to humanity are something like the justice system being built incorrectly in a dehumanizing manner. I find it heartless when a person feels like the people fated to suffer should just be damned instead of acknowledging a problem. Predetermination doesn’t make me into that type of person and while living several years with the illusion gone. I find that attempt something a person who hasn’t thought much about life (would say) while not thinking everything is determined.
