Why does gravity punish someone who jumps from the roof of a house? Free will is the choosing to jump. Isn't your immediate thought, "The result of jumping off the roof wasn't punishment, that was the consequence."
In the same way, every other act we make has a consequence. I don't go to work, I don't get paid. I eat too much, I gain weight. I drink more than a thimble full of wine, I go to sleep. Everything I do, I weight the consequences. I don't choose to go to prison, so I avoid acts where the consequence is prison. Free will.
