Why would she want him to be locked up? Yes he seems dangerous but has he done her any har...

this is like if a rlly rich neighbor forcibly buys a wild bear, and keeps it in his backyard, but lets it roam around the neighborhood where other unsuspecting families of all kinds live, simply because the bear treats him and others kindly and seems to be communicative with humans. there are no precautions set against the bear in regards to how he interacts with others, since they know nobody can stop him from doing whatever he wants. regardless if the bear is kind to them, it’s the fact that the guild basically lets him do whatever he wants regardless of the fact that they classify him as a monster and is letting him roam around other humans. i dont think it’s a matter of her disliking him or suspecting him, and rather more of a remark on the guild’s lack of responsibility and what they should morally do from a guild standpoint

(2) same thoughts when I read that psrt in the novel btw

Invalid comparison, he, who she thought a monster literally saves her life in the dungeon, left her there and starved for 3 days by their own fellow humans.
He who they thought a monster is a more kinder being then their own kind.
Bears dont cook full course meal for her, even give her a gift for visiting him home. He talk to her respectfully. Even being an excellent host. He send her safely out, and tell a trusted friend to send her home SAFELY.
She, the one who go through all that life and death situation, the only reason she can go back safely to her dear family in 1 piece, stomach and pocket full, saved by non other than a monster. Doesnt matter what he are, the fact that he save her, that will changed a truly grateful person perspective after all that.
She's the last person who should be saying all that.

nah i agree, from like an emotional or individual standpoint i totally get it, i just think from a larger institutional level, that was probably the thought process.
