Please distinguish the terms for me, please.
You ponder things. I ponder things. You meditate. I meditate. You read and research a variety of sources. I read and research a variety of sources. You come to your beliefs, conclusions, hypotheses. Ditto.
You started the OP with an "if" (second para.) and continued with many "ifs". I simply followed with my own: if you were God.
Free Will is something I have pondered, researched, and meditated on, so, just like you, I have some thoughts and conclusions I have come to. I'll explain it this way:
Free Will is a broad "program", a gift installed to implement freedom to choose in mankind as a whole. It has overtaken instinct alone in our species.
Simple will is individual. It is like a drop-down menu choice. It is limited by the choices that are available to you. Example: I have the will to work toward a goal. I will make individual choices that will facilitate my achieving that goal. However, my simple will may not be enough. I could become paralyzed. Now, I cannot become the marathon runner I wanted to become....but perhaps, I can choose another field. (Stephen Hawking comes to mind.) I have individual choices.
So, if free will and simple will mean the same to you, then I guess I misunderstood your OP.
