I read the raws without understanding a damn thing and I am shocked that Eidia was actually the leader of the Underground. It's also nice to see that she still holds hope that her friends are still alive, despite having zero information on three of them.
I will say this; I'm honestly glad the opposing side (who are also religious) is not the Catholic church. Because there have been so many stories where the church is evil. Like, come on, there are a handful of religions in real life already. Just pick something else for crying out loud.

Hmm, I don't like her brother. I mean, I never did but I don't like her brother in relation to his boyfriend. He's far too controlling, to the point that the lad had to sneak out.
MC only wanted to save the beastmen because it's a mostly-neutral territory. She has no reason to do that now, so she doesn't care. It's not about morality and never has been.
For people who complain about how they only care about her after finding out she's a good cook; that's the whole point. The culture in this family is that your worth is determined by how well you are with food. She's not the only one under this stress, as we see in the flashback.
