To me a more egregious example of them trying to present some kind of morality or object lesson is if you give the githyanki egg to the society of brilliance. Apparently it hatches and the baby githyanki wants and is able to kill them all. Just because.
I might be wrong because I never gave them the egg and only gathered what happens to it from the web, but don't the scholars raise Egg-boy to be a morally good person but do so in a way that shows themselves to be cruel and amoral? So they garner his righteous anger and retribution and he kills them because they are evil?
