This is just another example of the all too common use of "Oooh, Deep Timeless Updateless Reflective. Cooperate, morality, hugs!" when the actual situation would prompt a much more straightforward but less 'nice' solution.

(It may sound unlikely, but I'm almost certain I'm indifferent to conclusions on things like this in the sense that I'm mostly interested in what decision theory itself says, and much less in what I'd do in practice with that information. The trouble is that I don't understand decision theory well enough, and so going against emotional response is no more comforting than going with it.)
