"Being motivated by wanting to not be a bad person is something I think of - as particular flavor of Good that Civilization is kind of ehhhhh about, not least because it goes along with people who are sad that they can't destroy all of reality and make sure nobody ever has to stub their toe again?"
"Hypothetical Keltham definitely wants both Carissa and Yaisa, that's what makes the setup even be interesting. The thought that writing Defect would make him a bad person isn't particularly occurring to him, though, that's just not how he parses things. The situation where Broom wrote Cooperate and Keltham wrote Defect is just one that Keltham intensely does not want, and for him to avoid that is no different than him taking a gift of a million gold pieces if those are on offer. He wouldn't take the million gold because it would make him a bad person to turn them down, he'd take them because he wanted a million gold. There's no arguing the utilityfunction."
