Free will can only be discussed when everybody in the discussion is on the same page with the same terms and definitions.
Free? Free from what?
Will? What is it? How is it?
If you correctly identify the "will" you discover the secret hiding place of God in man's consciousness.
But, few people who participate in these kinds of discussions are willing to DEFINE their terms. The results are that the hidden presuppositions pop out looking like conclusions.
Kind of like stacking the deck and finding a royal flush in your poker hand.
Remember, the Uncertainty Principle isn't anything more than a description of what happens when you bump something.
You can only "observe" things by bumping them with either light (photons) or electrons, etc. That process of bumping disturbs either their path or their behavior.
Aristotle was way ahead of things back in the 4th century B.C. He discussed things in terms of their natural state or nature.
A thing is defined by its nature. Nothing escapes its nature. A rock does rock things and a balloon does balloon things.
Choice is purely a matter of semantics that falls within the boundries of the nature of man.
Think of it this way. A man alone on an island has a choice of things to eat determined by what is available and what he can find and obtain. He won't eat rocks or sunlight. His nature at work.
The only ultimate "choice" is whether to eat at all. By not ending life; we choose it.
