Are our choices fully determined by prior causes/environment/biology, and if so, how should we define morility/moral responsibility?
If determinism is true, then every choice you make comes from causes you did not choose. Your biology, your environment, and your past experiences shape every decision.
If all of those factors were exactly the same, you would make the same choice every time. That means you could not have done otherwise in any real sense.
If that is the case, then moral responsibility has to be redefined. Instead of saying people deserve blame or praise, we should focus on outcomes. Punishment should be about preventing harm and shaping behavior, not retribution. The goal becomes managing causes, not judging people as if they created themselves.
