The defection is a single action though. You can't extrapolate from a single data point. And, again, there aren't any Stormtroopers who refuse to defect.
Maybe this is a matter of your misunderstanding the underlying meaning of Austin's words there and running with them? I dunno. It seemed pretty obvious to me what he was talking about. I'd suggest that since
nobody else in the movie defects from the First Order, there's a decent example of him doing something
nobody else (in the First Order) does.
Especially when you consider Kylo Ren, who is offered a chance to leave the First Order, and is offered forgiveness and a fresh start by
his own father, and he refuses that. Kylo had MORE reason to leave, a better incentive, and a better escape plan, holding his hand out to him, and he didn't do it.
And then Finn, after realizing he always had something to fight for, he just needed to embrace who he really was in order to do it, fights that man who couldn't do what
he did.

You can't handwave the story importance of the only Stormtrooper we've ever seen in a Star Wars movie deciding they need to escape that atmosphere and do better.
You and Doey are literally trying to mount an argument against someone
choosing to not be a Nazi as if it was
a moral weakness.
It's kinda fuckin mind-boggling, Brakke. It's like the (il)logical conclusion of the silly argument people were kicking at about a thread back where Finn should have been more torn up about shooting soldiers in an army that blew up five planets in one shot.
