Becca, thanks for your thoughtful comment. I agree that the behavior can be very well hidden. Should we (society) develop a better way to discover inner tendencies that have not yet surfaced? Or do we let them alone until they appear? What if someone is physically or psychologically damaged because of that tendency? What if Kirk had turned out to be a murderer or a rapist? What if he had abused one of the critically ill children for whom he was providing care? These are all questions that I contemplate with some frequency.
