I genuinely think the authorially intended reading of Guts’ decision is that it’s complicated and there are multiple reasons Guts is choosing to take Casca to Elfhelm over revenge right now. It’s not a simple matter of Casca straightforwardly being more important to him or just choosing Casca over Griffith.
Hopefully this is the kind of answer you’re looking for, idk the subject is a little broad. I’ve kind of said this in some other posts too but I think it’d be handy to have a nice and orderly list to link to so I’m just throwing it all out in response to you.
So here are the various complicated reasons I think Guts has for going on his take Casca to Elfhelm quest:
1. He gives a fuck about Casca. He gave a fuck about her and saved her life even back when he hated her, because she was his comrade, and I’d certainly hope he cares about her now.
2. Elf cave is gone, and he’s not so shitty a person that he’s just going to abandon her in a field for ghosts to eat.



3. He is aware that revenging made him a worse person and he wants to be better. Guts at his best is someone who does not abandon his friends and family but rather stands by them in their hours of need, and he wants to be that person again.

Like, yk, abandoning people or staying with them is kind of Guts’ major thing throughout the story.
4. He is longing for a piece of his lost past, and Casca represents the Hawks.


Additionally suggested by how every time he pictures her from the past, after that last pic, it’s as a Hawk commander.

And statements like this:

And the general fact that he’s trying to “force” her sanity back despite forboding warnings and actually contemplating on page how awful it might be for Casca, suggesting that it’s less for Casca’s own sake and more Guts’ selfish need to regain some of his happy past.

5. Griffith looking human and sexy makes him forget his urge to kill, lessening the temptation of revenge and probably making Guts doubt his ability to follow through.

nuff said
6. Guts’ whole revenge campaign was less about revenge and more about making himself feel better and getting Griffith’s attention. Last time he saw Griffith the dude declared that he was completely free of his feelings for him and then “deserted” him in the snow lol. This has also lessened the temptation of revenge – now pursuing Griffith feels extra fruitless, because Griffith (claims he) doesn’t give a fuck.
quick illustration:
swinging his sword making him feel better

guts wanting attention

7. He feels guilty for abandoning Griffith back in the Golden Age and refusing to abandon Casca (this time) is a way to make up for that mistake.




8. Like the Beast of Darkness says, Casca reminds him of “the wound Griffith left” because he wants to keep feeling the pain he caused him. Both because it helps simplify his conflicting and confusing feelings into rage, and because, harkening back to point 6, imho it’s a masochistic reminder that he meant enough to Griffith for him to be worth lashing out at.

I mean consider the context of some discussions of wounds in berserk. “I too want a wound… that I can say you gave me.”
Or Griffith tracing his shoulder where Guts’ sword failed to touch him, maybe:

Anyway regardless of how suggestively that statement can be taken in the greater context of Berserk and wounds, there’s definitely some truth to it because it’s what Miura gave as the reason he didn’t kill Casca:
9. He’s still planning to return his focus to Griffith eventually. He hasn’t so much given up his revenge quest as put it on hold. It’s probably easier to say “not now” to himself than to say “never.”


10. Narrative convenience keeps him on the straight and narrow. eg:



cue Guts literally passing right out ten seconds later. it’s pretty easy to decide to get on a boat instead of get revenge when you can barely stand and going for revenge would be literal suicide. and even then Guts needed Serpico to step in and tell him not to be a dumbass.
Soooo yeah I think that about covers the various reasons Guts has for putting aside his revenge quest to take Casca to Elfhelm, which add up to smthn a lot more complicated than choosing Casca over revenge. I contemplated adding another section that’s like… a giant list of Guts utterly failing to prioritize Casca or demonstrate that she’s “more precious than Griffith” lol, but I might just do that in a separate post next time I’m feeling salty.
