Does anyone else have suspicions about the "several weeks" timeframe that the Lady 3rd has given for the transforming of the Babyeaters?
What can the Superhappies do in several weeks, regardless of their hyper-advanced and hyper-advancing technology? I suspect not much other than kill off most of the species. A quick genocide will decrease more suffering on the long run than an arduous peaceful solution.
Genocide seems even more likely since lady 3rd told Akon that his decision would be identical to other human decision makers.
The Babyeaters of the ship decided not to cooperate and they were destroyed. The rest of the decision makers of the Babyeaters will not cooperate and will have to be destroyed (in the mind of the Lady 3rd).
So at this point, the Confessor shocks the Administrator and they allow the Superhappies to go on with their genocide of the Babyeaters. Unavoidable and humanity would have done a very similar thing anyway. Then destroy the star and go back to Earth to prepare to meet the Superhappies again in a few decades or so (since their progress is a few orders of magnitude faster, humans can easily expect to see them again uncomfortably soon). Preparations would include eliminating suffering and such so that a new war would be avoided after the next meeting. Why on earth haven't they eliminated pain anyway? :)
