BPD is more about trauma than it is genes. Neither of her parents seem BPD anyway. Bianca ended up the way that she did because Kim's parenting style is so laissez-faire. I am certain that she loved and cared about Bianca more than we can even imagine, but that doesn't negate any chance of neglect. The worst kids were never the ones being beaten and tortured by their parents, it was always the ones with parents who were distant, careless, and never grew up themselves. Kids should not be allowed to do what they want, and despite the fact that Bianca occasionally got scolded, she had free reign. I'd say unrestricted internet access was the worst thing to happen to her in her important early developmental stages. She wanted to be cool and edgy but was a gangly nerd IRL as a kid, so naturally she was drawn to the online "alternative" scenes filled with Homestuck trannies with blue hair and gender dysphoria who listened to bad music. Those communities, while giving outcasts a sense of belonging, are filled with actual freaks who will tell everyone that every experience on earth is a symptom of mental illness and that it's cool as fuck actually, they will post porn like it's breakfast, they will "call out" each other's behavior as "problematic" as a covert power struggle, they will compete to see who is the most tortured and fucked up because they take pride in it since being fucked up is how they define themselves after feeling like outcasts for so long. Take the shame and turn it into your superpower that makes you the best. From there it just got worse.
Of course she found her way to r9k a couple years later. It was the logical conclusion. Going from smol bean tumblr self-diagnosed schizophrenic genderqueer with a tattoo choker to an edgy r9k self-poster is the girl version of finding 4chan through gaming communities. Bianca's mom can only be blamed so much, even if it's true that she should have kept a much better eye on her kid. It's not her actions that fucked Bianca up, it's her inaction.
