What is free will, and how does the Bible work in relation to law and justice to impede free will?

According to the Holy Bible, “free will” is something that mankind discovered it had access to after the “original sin” namely the eating of the “Tree of the Knowledge of Good and Evil” in the Garden of Eden. However, philosophy and science would agree that free will is the realization that any person comes to when they realize that they can physically do anything at anytime as long as it is within their physical and psychological capacity to do so. The Bible in many respects suggests that free will is dangerous in that it can lead people to do harm to one another, and in many respects without consequence if the offender is not caught and tried. Laws and commandments checking free will were given by God to the Prophet Moses in the Old Testament, namely the Torah, the Pentateuch, and the Law of Moses, which are all titles given to the first five books of the Old Testament. Many of the laws that are set up in today’s societies are heavily reflective of the Laws given in the Old Testament (namely The Ten Commandments, found in Exodus Chapter 20,) (Thou shalt not….), and even in the New Testament (Render unto Caesar) (paying your taxes, being a reputable member of society). Other laws such as giving 10% of your increase, namely your gross income, to God, (mentioned in the OT and NT,) are laws that check free will, both spiritually and naturally. Laws regarding tithing check free spending, increase loyalty to your church, and increase covenants with God as described in the scriptures. I hold that the Bible, is a significant source of the concept of justice in the modern world, excluding the governments that practice Sharia Law. The governments that do practice Sharia Law appear to take their Holy laws very seriously; they believe that Sharia Law has natural and spiritual consequences, and is an efficient standard for human behavior. Sharia Law is however, based upon the Holy Quran, which in many respects is derivative of the Holy Bible. In summary, the Holy Bible has apparently had a greater influence on the behaviors and affairs of mankind more than any other book when factoring in its historical, political, religious, and social influences. How has the Bible’s ability to check free will with its teachings and implications contributed to the checking of the actions or non-actions of mankind? Is it the promise of the glory of Heaven, or the threat of the flames of Hell? Is it the promise of a relationship with God? Perhaps it is that the Holy Bible makes people want to negate their free will in exchange for the opportunity to be a more decent, more reputable person through the study and practice of its teachings.
