The worst part of the brother's self-righteous bs and extreme violence, is I know when this is all said and done we're gonna be asked to forgive him and move on like it is nothing.
Getting a bit tired of the "my actions were not my fault, so please forgive all the horrible things said and done" trope that keeps cropping up in fantasy manga.
Still, maybe this will surprise me, and my complaint above will be rendered moot. We'll see...
