> No. Causality is all you need to identify who the criminal is. Unfortunately not. If your gets car stolen, without free will, you can't assign responsibility to the "thief", because you yourself were a causal factor in your car getting stolen: had you parked somewhere else, your car wouldn't have been stolen. Had society or his parents better supported the "thief", he wouldn't have stolen that car. Had your city placed that street somewhere else, your car wouldn't have been stolen. To designate the "thief" as the "singular" cause that's relevant, you need free will. |
Having laws (and the enforcement of laws) in place is something we believe to be the most effective input in causing the Bad Things to not happen. As such, having them and enforcing them is purely logical. We have decided that having someone "broken" in such a manner that these inputs are not enough to result in them not doing Bad Things need to be removed from the public, and do so.
Let's even step away from laws and assigning moral responsibility there. Let's look at interpersonal relationships.
I love my SO. I try to avoid doing things that hurt her, because seeing her hurt fundamentally makes me unhappy. It makes me unhappy enough that it outweighs the personal benefits of whatever decision I was making. We would all agree that not being shitty to your SO for personal gain is a morally correct choice, but this is still all a matter of causality. Either you have negative stimuli to it from something more direct, such as in my situation, or perhaps just because of social pressure and the desire to conform, but morality still comes into existence from the causal nature of reality. Free will is not necessary to explain it.
