Andrew, God could have stopped Adam and Eve at any moment. He allowed them to make the choice. Being allowed to make a choice does not mean you are free. Slaves are allowed to make choices by their master, yet they are still slaves.
Free-will is different than allowed choices within a confined area. Free will means the person is the master and not under anyone's authority. It means human will is greater than God's. It means that God is subdued by the human will.
Is your will greater than God's, Andrew?
No, it is not. God either allows your actions or He stops them. You are under the authority of God.
The Bible tells us that we are either slaves to sin or slaves to righteousness.
Romans 6
16Do you not know that if you present yourselves*to anyone as obedient slaves,*you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness?*17But*thanks be to God, that you who were once slaves of sin have become obedient from the heart to the*standard of teaching to which you were committed,*18and,*having been set free from sin,*have become slaves of righteousness.
