I'm not sure if it was in this thread or somewhere else that I brought it up but yeah you are right. If you actually pay attention and read between the lines, the implication of her brainwashing is darker than you might think.

But at the same time I think you guys are reading a bit too much into it (coping mechanism, not appropriate for her character etc.) when the explanation is rather simple. The writer just went with the 'that's hot' mindset. His whole portfolio is 'that's hot' regardless of whether people are comfortable with it or not, just look up his other characters. (I mean they marketed the game with bestiality and the writer bragged about on his twitter)

From Hasin to the Red Prince, even Shadowheart it is clear that this writer doesn't either have the skill or the wish to explore these topics in a deeper manner or with a delicate touch it deserves. That's why all of them devolve into cheep erotic novels. (And the sex starved redditors are going wild for it. 'I wish there were fully animated sex scenes' few redditors said, lmao)

As for the brothel (without Halsin) and the Mizora scenes, even tho I think those were done poorly and don't necessarily fit her character they are avoidable (and to an extent you can explain them away or just roll with it depending on your preferences). The main issue comes with Halsin, he is like that stupid marvel meme 'I'm inevitable' and that to me just shows me where the writers priorities lie.
