Eru created the universe and all the people in it.

So?

If you asked people 'whose opinions do you care about' lots of them will mention the creator of the universe, won't they?

Well, they can't exactly get clean data because everybody in Arda they could ask has probably been brought up being told things about whether they ought to care about Eru's opinions, but while the situation is not exactly analogous Elspeth contains plenty of contempt for hypothetical Earth divinity on the grounds that they have clearly done a shoddy job. She does not have her mama's memories from her mama's own perspective but she did still raise her.

So some people will hear Eru's will and decide they don't care. Other people on Earth do try very much, though, right, and even without much clarity about what their creator wants?

Yeah. It's kind of a mess, honestly. And leads to people being jerks at anyone who disagrees or can't live up to their standards. There's, like, Grandpa Carlisle, but he's a rare bird.

And he'd want to know what his creator wanted from him even if it was hard and unfair, right? So even if Elspeth objects they will keep on making it known.

Well, his interest in his creator's desires has a lot to do with believing they are not unfair.

Well, it is for the Elves to judge whether Eru is unfair!

Okay then.

...totally is though.

Yes, she's communicated very well that she thinks so. Does she want to go home now.

If they're all done having things explained sure!

They think incarnates make sense now!

Okay! They should be careful not to be too overconfident with that, even people who are incarnates can make huge mistakes in understanding others!

Noted! They've been erring on the side of caution anyway, and will keep doing that. And home?

Home!

And she is right where she left from.
