I mean...yeah? That's usually how these things go. Test of character and heart and all that, cold/hot reading, blah blah blah. If a jerk hit the bell, it'd probably be pretty obvious their a jerk to begin with and they'd probably mess up the bell so it'd sound discordant. "Wow the bell says you're an asshole, crazy." But if a rambunctious, but otherwise fine kid hit the bell really hard in the same way to make the same sound they'd probably go "you're such an active kid, but be careful okay?" or whatever.That's fair, although I'd argue that that raises some separate, equally troubling questions haha.
We're told by characters in the region that the bell's sound differs depending on the person ringing it, so either it's just like a confidence game/psychic reading thing where it's all in your head and an authoritative third party can just infer whatever they like depending on your vibe (in which case there's a lot of potential for exploitation), or there's actual random variance in how the bell sounds (in which case people who get unlucky have been condemned by a bell for no reason).
I mean it's a work of fiction so of course it's right on the money and presented very mysteriously and meant ot be taken as a literal reflection of our character, but it's likely not a literal magic bell
