Actually, Endwalker doesn't frame them as that. There's one guy wanting out, sure, but everyone else is basically lamenting 'we put everything on the line, why isn't this working'. Which I can absolutely understand from my own life; it really sucks to put your all into something and then see it failing. We're also seeing them at a real low point, so it's impossible to extrapolate back to guess the overall mood of those souls at a time that was less dire.
I think what happened is that we saw people in a situation that some of us read as 'trapped', and then therefore wanted to free them because that's the natural response to seeing someone trapped. But in that point, we only had a conversation with one person: Hythlodaeus. And he seemed pretty chill about it all, really; he made his choice and never once regretted it. In fact, it's an outlook reflected by the Watcher, still believing in the heavy decision they made. Granted, both of them were sample sizes of one, but in a character-driven story, 'the testimony of one dude with a name' is kinda the most valuable way to gauge how you're supposed to feel about the group they're representing.
I don't think they were trapped, I think they almost all wanted to be there. it's just that they were hoping for a better result than Fantastic Dan and the Reaper Man trying to jack their Megazord.
