To be fair, in the SKE documentary a few SKE members mentioned Jurina's behavior at 2018 SSK and how they think/felt it came across as abrasive to members outside of SKE because they aren't familiar with Jurina or understand their group mentality. I'd have to rewatch, I believe one of them specifically mentioned how in SKE they are comfortable with criticizing each other and they felt the other groups weren't and may have taken comments directed at them badly. I feel if it was brought up with the intent to justify or explain Jurina's behavior, it's likely her behavior was rubbing the other groups the wrong way. I do think the doc did a good job of giving context for her actions. The issue with Sakura is never directly mentioned, so who knows beyond what J said. I also watched an English sub of the documentary, so ymmv on the translation. But anyway, sorry to keep dragging this here. I hope she gets well enough to have a good send off.
