«Deserve’s got nothing to do with it». —William Munny, Unforgiven
Notions of fairness are just part of the moral code that we give our otherwise senseless lives. It is thankfully in our nature to want to make living with others based on ideas of social cohesion. Otherwise life would be hell for all of us.
Unfortunately, some people divert from our understanding of socially acceptable behavior and need to thus be kept at bay.
I don’t find that the erroneous idea of a «free will» is more than just part of that moral code we’ve adopted as inherently social animals. We want to make sense of the world around us. We want to be able to make moral judgments based on ideas of agency, and therefore decide if a given behavior was «good» or «bad».
Yet, to me there’s no difference between a person who murders someone for money or the psychotic person who kills their child, because a voice in their head tells them to. Both of these actions are completely socially unacceptable. What’s more, they’re both based entirely on states of matter in the person’s brain. Yet, we put one of these two in hospital for safekeeping and intensive treatment. And the other one ends up in a highly dysfunctional prison system, without treatment and frequently with the expectation of being subjected to capital punishment.
Christopher Hitchens once said «I don’t have a choice but to have free will.» I always took this as a nice encapsulation of the conundrum and self contradictory concept that is the idea of a will that is somehow free of those states of matter.
