It all depends what the reason is and how it came into existence. You have implied that our conscious awareness has no input on the matter and the reason behind any conscious choice occurs in our subconscious before we become aware of it, in which case it is not really a conscious choice at all. Can you at least comprehend that my contention of the soul invoking the reason is NOT a random event, but that it is an alternative explanation, even though you disagree with it?
You don't appear to have even read what has been said to you - and have posted a totally unrelated response.
Look, even if we accept, for the sake of argument, that there is a soul that it is making "free will" choices, this soul still has to arrive at its decisions somehow - using some process - and it is the nature of that process that is the point. It is logic (not whether it's a soul or material) that dictates that any such process can only consist of deterministic (and possibly some random) steps.
Whatever it is that feels to us like thinking things through and making a decision, is actually a complex set of deterministic (with possibly some random input) steps. This is a logical constraint that has nothing to do with whether 'we' (our minds or souls) are material or something else.
