If you played her road and paid attention to how she was raised and how she gradually changes when she's with the MC, you'd know that's bullshit, it's an act, she learned to survive in a harsh environment where the weak doesn't live long, just the scene in Ep6 when she goes back 'home', her mother doesn't even recognize her anymore, then the pencil traits of her height at ages 5-6-7, imagine that kid growing in that place... doesn't excuse the way she acts (especially in the 1st season), but it sure explains. She just doesn't know how to be anything else, but her walls are melting fast, when with the MC, since Ep6.
I've known some people coming from those background, a couple of them managed to get out and get a life, sorrily most just repeat the same cycle. I come from a very, very dysfunctional family and one of my parent was a monster, had trouble for a long time with relationships, used women then threw them off, you learn to hate people around you because you hate yourself. Well, everyone is salvageable, and I'm sure it'll be the morale of Quinn's story.
I hope for a redemption act, and I'm sure DPC leans towards that, her theme songs are pretty indicative for that, her scenes too. Doesn't mean it will end well, though. It's DPC after all, same could be said for every character in the game.
Now, you can still hate her if you want, that's your business, but comparing her to Dawe, man...
