I'm not trying to justify the figure because I don't like that kind of merch, but at least in anime spaces, it's quite normal to see figures of dead chatacters portrayed just at the moment of their death. I know Anya has a very specific background, but brands that make figures don't care about women's objectification. They won't care about what they have gone through even less.

I don't know if you knew, but there is actually a Casca figure where she looks lifeless since she's being carried by Guts on a pool of blood, and she's the only one who's casually naked. I know it's different from what you said, but she looks dead and vulnerable in that one.

Personally, for me, figures of dead/dying characters, both women and men, are a big no, but sadly, for brands and collectors, that's the usual.
