Korby's is a situation any man could find himself in after, say, major surgery or divorce or loss of job. Is he still the same man? Having factually lost something (say, a leg), is he a lesser being now? Friends have difficulty hiding their revulsion over the visible change - should he wait till that blows over, or is it time to google for "hangman's knot"?
The transformation into a machine man gives this particular take an interesting flavor, but it isn't all that exceptional a situation deep down.
