Yes you do have free will so did Adam and Eve. They did get punished but they had freedom of choice . If they did not they would not have choice to eat the fruit. They were told not to eat it and told that the would die. Then they were tempted and they had the free will to eat it . Even with the knowledge of punishment we still have free will. When they ate the fruit did God Kill them no. He asked them who told you that you were naked they said the snake and you no the rest . But what God did next was made them garments to cover them. He still loved them he told them there punishment and they lived happily ever after until they died. The punishment does not take away free will.
