Nah, you don’t have to use proof or anything if you don’t want to because it’s a highly interpretable topic, and I feel like we’ll reach a point where we will be talking in circles! (Besides that’s a lot of work!! If you want to do it, I encourage but pls do not feel like you have to :((( )
Now that you’ve given more clarity as to what you mean by the state of Clair, I understand why you’ve reached that conclusion. It’s personally not my interpretation, but I get the argument and I like it. It’s well thought out. .
My reasons for claiming Sayo doesn’t have a fixed morality is because, in the story, there are points of conflict between her personas regarding murder, manipulation, and death. Society tells Sayo murder is bad, but Sayo tries to warp society around her goals by re-writing reality through “magic”. Shannon and Beatrice are heavily invested in the fantasy of reverting everything to zero and taking it to the Golden Land. Kanon is invested in the reality that murder is bad.
Having morality doesn’t necessarily mean your actions are good. Having strong morality just means you stick to a code of values. I argue that Sayo doesn’t have a strong sense of morality because she argues with herself constantly about what the right decisions are. She’s inconsistent.
Sayo spends a really, really long time establishing lore to create her Golden Land ideology. Beatrice’s background was used to disguise the ugliness of Sayo’s reality. It was a coping mechanism, but it extended beyond that when she tried to use it to justify murder. Sayo tries to create her own standard of ethics where erasing Rokkenjima’s sins becomes an almost religious conviction.
Yet, she can’t commit to that because she knows it’s fake, and she knows the Golden Land is just a land of the dead, and she knows its a code she established to serve as an excuse-- Even so, she wants desperately to make herself believe.
Kanon versus Shannon is a magical interpretation of Sayo fighting between her own made up morals and the morals society gave her.
This is my reasoning.
