You will have to understand that not everyone has the same mindset as you think. Minami already said that in the early chapters during Yanuma's sudden outrage. He already said the same thing before that they have to move forward and leave the past.
But then, some unknown group keeps attacking random people like Kamioka and Teshimano so they got no choice but to confront all of these situations. The truth behind on the war and the mastermind behind it.
In chapter 83, Yamada already wants her way out of this and yet her memories of Patty still inside of her and can't do anything about it. She still suffers from PTSD.
Seriously, this is pissing me off. Not a single one of them bothers to just say, F*ck all this. This is my life now, the war is over. No point living in the past.
Like for real, even the priests are dumbasses.
