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.
YMMV: The Drowned Cities
Complete Monster: Sayle who doesn't care about what he's fighting for and is more interested in killing and hurting people. He's the one who started the UPF's practice of mutilating all of those they capture, a practise that then spread to the Army of God and the other soldier boy groups. Sayle notes that he did this on purpose, as it would make his soldier boys less likely to surrender. Worse yet, he actually manages to violate the soldier boys' own code of morality (such as it is) when he recommends to Colonel Stern that they torture and mutilate Mouse/Ghost, now one of their own, in order to hurt Mahlia, whom he feels he owes for embarassing him.
Jerkass Woobie: Ocho. Mahlia herself has some traits of this.
Moral Event Horizon: Stern crosses it when he has Mouse/Ghost mutilated in order to get to Mahlia. Sayle crosses it in his first appearance, with his treatment of Mahlia.
Tear Jerker: Mouse's death, and Mahlia and Ocho's reactions to it.
