Idk. There isn't one I guess. This particular moment stood out to me bc it's the main character who's responsible, there's a lot of other things I wasn't happy with. Writers don't seem to take r*pe seriously in general, two examples of it I can give are trickster punishment for Latverk and those minotaurs with the doppelganger in Camellia's quest.
Most of the "heavy" stuff in WoTR feels unwarranted to me, I don't even know how to explain it. Just mindless violence used for shock value. It would be fine if the tone was consistent, but WoTR can be so comedic at times, the mood swings are too much. WoTR is simultaneously juvenile, naive and mean-spirited. There's no deeper meaning behind all the gore, it's just there.
I've seen ppl say the edgy writing is intentional but like is it? Did I really have to read how that Azata dude wants to f*ck Arueshalae's eyeholes? Was it supposed to be funny? Again, she gets her fairytail ending after that, where is the consistency? Where is the cohesiveness?
I've always laughed at ppl saying PoE was too dark now I know how it feels
