"Disregarding the introductory line about the serpent being crafty, then yes, it could mean that."
But God, Satan and Eve never wrote that line about him being crafty.
So the author (who wrote Genesis again? Moses?) has no right to imply that he is skilled in the art of deception. From what i understand he led an uprising against God. He didn't lie to the angels that joined his cause, they agreed with what he stood for.
Where is the evidence that Satan lied before the temptation of Eve? Because without that, the line about him being crafty cannot be valid.
EDIT: I'm passed by posting limit for today, but you're 100% right about how Eve resisting the temptation would also mean that she'd be exercising her free will.
