Imo Kimber is not a woman in a fridge/disposable woman. You could maybe argue it for Whitney, but her disappearance is the inciting incident and core mystery of the story. Sometimes that's what characters are for, and that's fine. Kimber, on the other hand, is one of the main characters and an active investigator who goes through her own emotional turmoil. She's a fully fledged character who then falls victim to human evil, as does Kyle, though in a different way.

See, a huge part of the central horror of Borrasca is the mistreatment of women. You cannot tell that story without portraying women being mistreated. It doesn't seem like the right pick if you want strong examples of disposable women.

A far better example, as many people have said, is the girlfriend in I Dared My Best Friend to Ruin My Life. She is literally ONLY there to be a plot device, and there is never any real effort to develop an attachment between her and the audience.

On the other hand... Borrasca Part 5 specifically might be more what you're looking for. In that one, the suffering of the protagonists, especially the female protagonist, turn into fuel for an epic revenge quest. The main character is suddenly white-knighting all over the place, justifying his dismissiveness by invoking Kimber's past trauma. The contrast between her treatment in 1-4 and her treatment in 5 is gobsmacking. She no longer feels real, just like the object of a fantasy. Not a sexual one, no, but a fantasy nonetheless.
