Idk I too want better for Casca but I really dislike the hype for Casca potentially becoming an apostle, these users put it far better than i would:

I skimmed these posts to see whether there were any points made that I felt like "responding" to, and there's a few.

First, Casca being a good person has nothing to do with anything except people not wanting her to become a monster, which I obviously don't vibe with because I think the concept of a good person becoming a monster fucks hard, which is one reason I like Berserk a whole lot. And I think a potential Moonbaby sacrifice would fit perfectly with one of the "good person" sacrifice examples they give: the 'person you loved the most and hated the most' sacrifice motivation, since it's intertwined with Griffith in some metaphysical way and it could be a two for the price of one deal. It's almost too on the nose.

Second, I don't think it necessitates Casca joining Griffith. Griffith seems to be out of the Godhand now, incarnated on the physical realm, presumably no longer presiding over sacrifices, and my favourite worldbuilding pet theory is actually that the godhand and Griffith will be at odds. Something's gotta threaten the godhand's existence since something wiped out the last cycle that we saw in Skull Knight's memory, and an incarnate fifth that appears right on schedule seems like just the thing.

Third, Casca's apostle trauma is, if anything, a sign in favour of her becoming an apostle since like, everyone in Berserk is at least tempted to symbolically become their abuser/rapist/nemesis as part of gaining power, eg:

Why can't Casca get in on the interesting and complicated moral and emotional greys here? This is good shit, I want it for Casca. I want her to be tempted to become what she fears, to escape her own sense of powerlessness through abandoning her morals. It's just a more direct version of Guts wanting to become a monster since that's rooted in rape trauma and both the narrative and Guts himself equates monsters to both his rapist and abuser.

I didn't see them mention the fact that apostles are compelled to love Griffith which to me seems like one of the best arguments against it (though again, I skimmed so maybe I missed it), but Ganishka resisted that, and Casca has a long history of repressing her love for Griffith so I think it could actually be a neat, and overcomeable extension of her human feelings.

Another big and better argument against it, particularly after the last couple chapters, is that Miura clearly just did not give a shit about Casca lol. And I mean I already knew that, one reason I thought the apostle Casca theory held water is that it would be a way for Miura to avoid writing Casca's trauma realistically and instead veer into one big dramatic moment followed by fantastical metaphor while keeping her a less nuanced plot point, albeit a more active and fun one than she had been so far. Instead his way of avoiding writing Casca's trauma realistically was to have her faint any time she thinks about it and then take away her personality AGAIN. So yeah, unfortunately I just don't think Miura wanted Casca to be badass and actively affect the plot. Idk if he ever knew what to do with her after deciding not to kill her off just to motivate Guts post-Eclipse.

Finally I just don't know if there's really time for that anymore. My vision was an Empire Strikes Back style end of second act downturn. Casca becomes a monster and sets a new arc in motion, Guts falls into despair and succumbs to the armour, shit gets real and interesting again for a while. Instead Guts' second act downturn is being mad that Griffith is still a god lol. She could definitely still go apostle at the climax of the story, and you better believe I'm still rooting for that, but idk if it'd be as satisfying lol. But I guess we'll see.

Anyway yeah you're free to disagree with any of my hot takes, but you're not gonna convince me Casca shouldn't become an apostle, because my reasoning ultimately boils down to "I would enjoy it." I would certainly enjoy it a hell of a lot more than fainting damsel in distress Casca which is what we're dealing with right now lol. If your reasoning boils down to "I would not enjoy it" then I probably won't convince you either, and that's fine. We'll find out what's going to happen eventually.

And finally I want to err on the side of caution and make it clear that I have no interest in arguing with the user you linked, and I hope you're not planning to be like, some kind of anonymous go-between linking posts back and forth. I used the linked posts as a bouncing off point to explain some of my reasoning, and that's the end of it as far as I'm concerned.
