I think you're making too much assumptions here, based on your generosity for this story.
Everything you wrote makes sense, in an isolated bubble that's unrelated to what we've seen thus far in the series. Right now, all I can see is the author bluntly showing to us a bunch of insane characters so we'd feel fearful for the MC. I highly doubt the queen, or anyone else for that matter, is involved in this maneuver. I believe the queen even gave up on the Sperados as a political tool.
That only leaves us with a bunch of wacky-doodle characters that are solely there to create contrived and artificial drama, tension and suspense.
Which, again, leaves me disbelieving completely that the commoner was actually cursed. I am willing to bet on it. As I said, it makes no sense in terms of storytelling, to give out so much information, but also hold out on it. We were bluntly told what the evil plan was, but we're not being told "why the commoner won't say anything". It's just a bunch of shitty writing, imo.
I may be wrong, I haven't read the raws. But it sure as hell wouldn't be the first time I saw this sort of unnecessary form of writing. I would've much preferred if we were only given very subtle hints of what the Sperados' think, and desire to do. Nothing blunt or explicit. We'd know what the MC knows. That'd leave us in her shoes, which I think is much more preferable overall.
