If you disregard the role of conscious awareness, there is nothing which can perceive a desired goal...
You will certainly be conscious of a desired goal but the reasons why it becomes the (most) desired goal are not actually under your control at all. All you can do is resolve any conflicting desires by weighing up how much you desire each one.
As has been pointed out before, many, many times, your wants and desires are what they are, they are not things you can change.
...and there is nothing to actively guide and validate the thoughts involved in reaching a goal.
As has also been pointed out, it is unclear to what extent and in what way consciousness is involved in those processes. If we take the multiple drafts view, for example, consciousness is more about how things are 'documented' in memory. Of course there will be feedback to future choices (stages in the same one) because memory is and important input (and also starts a fraction of a second ago).
However, I digress because you haven't addressed the point. This kind of vague hand waving is does not explain how the role of consciousness affects the credibility of an argument.
In fact, without conscious awareness there could be no thoughts! Do you understand the problem?
Depends how you define thoughts. Also, I didn't suggest that we could do what we do entirely without consciousness (although some philosophers would disagree) just that its exact role is not a factor in the argument about 'free will', in the way you mean, being impossible.
There is no dichotomy between an "inevitable reaction" and a "conscious choice" - regardless of what role consciousness plays in making the choice.You are your conscious awareness...
I'm far, far more than that.
...it defines the reality of your existence.
Gibberish.
I believe you are using completely the wrong approach.
Try starting off by accepting that our ability to make consciously driven choices rather than unavoidable reactions is a reality. Then seek to find out why it is a reality.
As I said, I see no reason at all to choose between "consciously driven choice" and "unavoidable reaction". Until you can show in some way that they are mutually exclusive, this is just a
false dichotomy fallacy.
You also seem to be suggesting that the best thing to do is start with blind faith and superficial intuition and then try to make some sort of sense of it. No thanks, you are a horrifying object lesson in what can happen when we abandon reasoning for blind faith.
