These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Jerkass Woobie: The monsters who treat Wallace rudely as he tries to do his job as a social worker. As Louise explains, they don't hate him personally, just what he—as a human from the richest district—represents (i.e., discrimination), so of course they don't want him around telling them how to live their lives.
Charlie in particular is an enormous Jerkass and it's difficult to sympathize with him, even after Louise explains how hard things have been for them. This is probably because his first instinct upon meeting Wallace is to attack him.
