If this was real life, and I had 100s if not thousands of years of history with them, I actually don't think I'd hate them; specifically the Mom and Raphael.
I DEFINITELY would hate Azel and the rest of the family, and I would most certainly hold a grudge against Mom and Raph, but not want to murder them, that's a lot. I would most certainly hold a grudge, and definitely NOT be at college let alone around them at all (living with them is an even bigger no) but at least they tried if you ignore the incompetence of how they tried and giving up for 50 or so years
. And then realistically I'd assume they wouldn't act like lobotomized zombies towards me saying I was tortured the entire time.
-As terrible as it is people like Azel would most definitely be a thing irl in the way she teases sensitive topics and yet tries to have you like her at the same time (I've personally dealt with someone like that and they are on the top of my shit list to this day).
-Mom would be your overbearing yet incompetent parental figure, perhaps too spoiled in life to actually know what to do on an emotional level with how to cure a broken child. Notice how her go to was to hire a therapist immediately (throw the burden onto someone else), buy clothes (trying to uplift with gifts, textbook broken privilege, I mean; she's THE Goddess), sending away to college (believing the only method is instead of spending time and mending, making other "unknown" people do it for you. Almost like throwing a phone or tablet in for parenting your child). All of which is backed up on the way she carries herself in the flashbacks. People like her would most certainly be realistic, save for the lust thing but that's power based.
Be that as it may she has her (two) good moments which is when she enters the bar to actually have a (semi) heart to heart, and the second happens when she's not even around; in a mention of her taking meds, so the loss of us clearly affected her. All of which are nice values and would be the primary reason I wouldn't HATE her or want to KILL her.
-Raphael is probably the best, again kind of has the same rich complex as her Mother but again, is actively trying. She tries to tell you their nonsensical plan immediately, and she was closest to us as a kid, you don't really shake off an inseparable hundred/thousand year history realistically, even if you do distance yourself it will probably naw at the back of your head for the rest of your life for cutting that tie (Another personal experience, with betrayal in fact, could only imagine 100s or a 1000s of years). And again, this is only if you ignore their blatant ignorance of what you went through.
The rest of the family I would HAPPILY murder without a second thought, would probably even relish in a few (like that black dude, forget his name it's not racism I swear). And others I would still murder with indifference or out of rage which would be like Raniel (the messenger chick, I believe that is her name). That's just my take though in terms of if I were ACTUALLY living this scenario.
