Punishment is not really about free will
The killing button Suppose I put you in an empty room with only one button. I don't tell you anything. You are free to leave the room without doing anything. Out of curiosity, you push that button. Actually, you pressing that button results in the killing of 100 people. However, you didn't know what will happen when you pushed that button. You were free to not push that button. Still, you pressed it. No people would have died if you wouldn't push the button. Most people and juridic systems would not consider you accountable for the tragic consequences of your action. The moral and legal responsible would be me for putting you in that situation. Would you agree?
