Saw this quote and now I'm just thinking about how Bianca internalized that, because she is weak in terms of whatever power system there is, she has to put herself through unpleasantness to make up for her lack of power.
For example, in her Jujutsu Kaisen verse, she's barely made it to grade two as a sorcerer. And she knows she can't get any better because of the way the power system works; you're born with it or you're not. So, she decides to go take a forensics degree and deal with all the aftermath of curses. And we know canonically that that's disturbing; for instance how Gojo describes it to Yuji before his execution or just how Yuji even experienced the sorcery world or how the light novel chapter in which Nanami and Gojo go on a mission describes the whole thing. And then there's the fact that a lot of bodies that come in are literally people she works with and knows and cares about. I can make a whole other post about her twin ending up on her autopsy table.
And, sure, she grew up in a sorcerer family so she shouldn't really be put off by it but this was in Europe. Europe, where they don't have curses like they do in Japan because Japan holds the monopoly on cursed energy. Sorcerers like her and Miguel are so few and far between that they basically make up 1% of the sorcerer population. And because of that, especially because of that, she feels like an even bigger disappointment because her lineage has basically been waiting for another sorcerer for ages. And they got stuck with her.
It's a similar mentality via other routes in her other verses.
But, yeah, she's just internalized that, because she's not stronger, this is how she can make up for it in spite of the fact that she's actually just a cinnamon roll.
