ok i just saw a post about crowley getting upset at that “did it hurt when you fell from heaven” pick up line bc apparently falling really affected him, but it says straight up in the book “Crowley (An Angel who did not so much as Fall as Saunter Vaguely Downwards) crowley did not give a single fuck
That’s one of the nifty things with Good Omens. Even though it’s told in third person and even addresses the reader directly, Gaiman and Pratchett did an awesome job toying with the ‘unreliable narrator’ idea. True, the Dramatis Personae says that. And later in the text it also says ‘he hadn’t meant to fall, he just hung out with the wrong people’. But there’s something more and more rare in fiction:
One will rarely notice it at the first read-through, so no one should worry.
Crowley deeply, deeply regrets falling. He’s telling himself that he doesn’t mind, and that things are a-ok, but he really regrets it.
Discussion, you say? I’m game.
Personally, I’ve always interpreted the “Saunter Vaguely Downwards” bit as a comment on his personality/morals.
He didn’t Fall by committing some sort of unspeakable act; he didn’t even do it deliberately - he “hung out with the wrong people”. And even though he technically Fell and became a demon, he didn’t really turn evil/malicious or change much as a result of it.
So it was a change in status, yes, and in my personal headcanon the act of Falling itself was rather unpleasant too, but what didn’t change much, at a fundamental level, at least, was who he was (On a more superficial level - and this is going more into speculation/headcanon territory -, I imagine he adopted certain traits/mannerisms to go with the demonic image he either felt he should be striving for or maintained to avoid being seen as weak/too nice by other demons/his superiors Downstairs).
So it’s entirely possible to both have him be not massively changed by the Fall, and have Fall/pre-Fall memories be an unpleasant subject.
