In that wonderful story (of fruit-feasts, talking snakes, and flying swords) one would have to define many words, and not necessarily in accord with WTS explanations (which assigns Adam a perfection that the text doesn't actually state).
Why not take the word "perfect"? If "perfect" means "fit for purpose", why does that require that Adam's mind be any better than ours?
"Free will" is another phrase that isn't found in the text. Freedom to choose one's own path instead of that of anothers'? Surely we are all hindered by our environment to such a degree as to know this isn't truly possible. Where there are limitations, is it really freedom?
I just thought I'd help throw in 2p to help you overthink this one
