They were in a different position than us before the Fall and, either way, they were not sinners until they sinned. Again, God does not create anyone as sinners -or He'd be the worst of sinners Himself.
We seem to be having a communication issue about sin. There is another party to sin that is missing from all your equations. Our adversary.
Adam and Eve engaged the adversary internally, just as Jesus stated in Mark 4:15. From that point on their narratives are not about only Adam and Eve as individuals. It is about them and their and our adversary who is within their equations just as our adversary is in our equations.
The moment God spoke to them sealed their fate. Satan entered their hearts and stole from them just as Satan steals from us all. Satan deceived them just as Satan deceives all of us. And every bit of this by God's own design.
ORIGINAL SIN was never about the people, but about our adversary whom we all remain subject to in our own minds.
The usual reaction to this information is typically cluelessness. Then possibly followed by denial that it happens. A tirtiary reaction is to revert to blaming and accusing only people, which actions of course are all of the devil or demonic reactions in the hearers. BUT Paul gave us the spot on example here:
Romans 11:32
For
God has bound everyone over
to disobedience so that he may have mercy on them all.
That disobedience is a spirit that is not the person. It is our adversary. The adversary who blinds the minds of all people, per Acts 26:18, Romans 7:7-13, Romans 11:8, 2 Cor. 3:19, 2 Cor. 4:4 and particularly
Eph. 2:2
Wherein in time past
ye walked according to the course of this world,
according to the prince of the power of the air,
the spirit that now worketh in the children
of disobedience:
Ye walked according to the spirit of disobedience.
All of us who "really believe" know this is a fact only in retrospect, after our eyes are opened to the fact of it. It does assuredly not mean we eliminated our adversary from our equations or the equations of anyone else.
Those who merely blame and accuse Adam and Eve are essentially still blinded to the facts of what happened to them and what still happens to every person.
They are oblivious to our enemy.
This fact is what led Paul to this conclusion:
2 Corinthians 1:9
But we had the sentence of death in ourselves, that
we should not trust in ourselves, but in God which raiseth the dead:
Our trust to get out of this dilemma is not ours to make. The promise of the Gospel is that some day this obstacle will be PERMANENTLY REMOVED.
In the meantime we all suffer the consequences regardless of the garbs we wear in denial.
As to the "devil fleeing" that does happen only when we realize IT is not "me." Just as it was "no longer I" for Paul in Romans 7:17-21. That assuredly doesn't mean we are no longer in battle.
