"Yes.
I.... think I have some kind of additional disagreement with you now about - if every human in dath ilan ends up with the same views on something as apparently-subjective as 'average utilitarianism', then I don't think it feels right to just assert that's all their unchangeable utility-functions - people don't have utility-functions, people are muddled and dath ilani society reliably resolves that muddle in that way, but I am not sure that's different than how Cheliax reliably resolves various muddles in various ways. I'd feel more confident it was a utility-function thing if it was, say, 85% of people in dath ilan.
I realize some utility-function things should in fact be overwhelmingly common among humans but this really, really doesn't seem like one of them especially given all the absurd-seeming claims it makes - you're going to say we should discuss this at INT-29 - but it seems like it would imply you should destroy perfectly good universes under a wide variety of circumstances, including if that subjectively sends everyone in them to Hell, so long as most of Greater Reality is much nicer than those perfectly good universes..."
