You seem unable to grasp the concept of the nature of our conscious awareness and what it is capable of.
That's because, as I see it:
a) you've failed to actually explain it at all
b) it makes no logical sense
At any one time we can be aware of many possible choices and many possible reasons for each choice.
Yes. And we can be unaware of further choices and influences, too, but yes.
Ultimately the decision of which (in any) of these choices is to be implemented is invoked by the property of our conscious awareness to interact with our brain.
OK, here we go:
1 - no, not necessarily
2 - our conscious awareness does not 'interact' with our brains, it's an experience of the activity of our brain
3 - even if that were the case, that's still not any sort of demonstration that the process is 'free' at any point from the inevitable consequences of prior activity
Yes, there is a reason for invoking the choice, and this reason originates in the conscious awareness of our human soul, not in the endless chains of physical cause and effect which trace back to the beginning of time.
Based on what? What reason is there to think that this process involves a 'soul'? What reason is there to think that a 'soul' of any sort exists in the first place?
Regardless of that, even if there were a soul involved, and even if that soul were interacting with the brain somehow, that doesn't resolve the ultimate problem with your concept of free will: each element within it is either deterministically resulting from prior causes, or it's random. Even the 'soul' operating somewhere else, and the interactions between that soul and the brain, each element of that is either deterministic or random.
How does that add 'free will'? Each element is either free (i.e. random) or it's will (decided based on prior events), but it can't be both.
