Let me ask you something. If someone put a gun to a woman's head and told her "get in this car," would it be considered a "free act" if she got into the car (because she was terrified of being killed if she did not obey?) As long as the doctrine of hell exists, Christianity is not a free choice. Hell is the gun to your head.
If I take certain substances, I will die from poisoning. By that logic, not taking poison is not a free choice. Knowing (or believing) there are bad consequences to certain actions does not take away free choice.
