I'm not absolving Riona of responsibility, I just don't agree with his philosophy of "everyone for themselves, the strong always oppress the weak and that's okay"
but the irony is that this philosophy of "everyone for themselves, the strong always oppress the weak and that's okay"
kind of prove that Riona is is weak and by being oppressed by quinn she basically didn't have a choice other than go along with whatever quinn's says
btw, there was even a scene about this in episode 6, after the thing get dangerous and quinn was robbed, Rio and Quinn had a conversation where Rio, wanted to get out, and Quinn told her she is to dumb for study and her way is the only way for both of them.
Quinn and Rio have / had a very abusive relationship. like a bad marriage, where the man/woman abusing his/her partner, and the opposite person has no way out, whether because of fear, or some misguided loyalty, it does not really matter.
the only saving grace is that even quinn see it it is her fault and admit she is despicable piece of shit human who not deserve saving and sympathy.
Her Stans should listen to her
