I see a lot of meta talking about how the John Verses are John telling the story of the leadup to the apocalypse with the most sympathetic biased self-justifying gloss to make it sound like nothing was his fault, and I guess that's why so many readings go for a hardline worst-faith interpretation of them, but.... I don't really see it.

When he tells about how he murdered everyone who had a gun, he could have played up the self-defense angle. He could have claimed he was scared, and he did it to protect everyone. He could have emphasized that he was killing cops, instead of emphasizing the civilians. He could have stuck with the story he told at the time, that he freaked out and made a mistake and hadn't meant to kill them all. He doesn't. He admits to mass murder, and he admits to having done it because he was angry. And he admits to still not regretting it one bit.

The story John tells just doesn't paint him in the best possible light. He does include all of the justifications he used at the time, he does explain why on earth any of this ever seemed like a good idea to anyone, and he does want to be understood, but he doesn't really try to sell it as having been right.

I really don't see the verse chapters as being John's justification. They're his confession. That's why they feel so good to condemn.
