No, he could have stopped her and Satan.
To what end? I am not understanding. Rather than project, what I think you mean, perhaps you might help.
I have no idea how it would have turned out. We aren’t told that.
However, God told them not to eat or they’d die.
So Adam, who was with her, watched her eat. My guess was that when he saw nothing happened to her, he chose to eat too.
It was after HE ate that the eyes of both of them were opened and they saw they were naked.
