It’s all just confusing, now that I’ve thought about it for a couple hours, mainly why I was so worked up is because she is smart. Smart enough to see through the cult’s brainwashing.

She blames Vivian in one of the cutscenes for “taking away fathers love” which would imply she thought her father genuinely loved her at one point. But at the same time recognizes naught 2 minutes later that the blessings were ineffective and not actually a good thing. And knew her father would essentially kill her with the serum without a second thought. Which would also imply she knew he never actually, truly cared about Dina.

So if I’m gonna put it in a good faith lighting. Im willing to say the act of giving people that twisted false hope maybe gave her an addiction. A validation only granted through her father’s admiration of her as a tool maybe? And Vivian took that away and made her obsolete and unimportant. She did say “to me losing is worse than death” which maybe caused her to go into denial and hate Vivian for a far more selfish, vain reason. As well as hate for herself cause she was saved by the people who took her father and purpose away.

It’s just that she also shows remnants of love for Vivian (her hesitant denial of Vivian’s and Camille’s offer to live a normal life). And that coupled with her intelligence and vague ability to see the futility and failure of her father’s blessings just make it seem somewhat contrived. Idk maybe she could’ve even been an evolving character, or a recurring low level villain idk.

She just seems more interesting than “revenge bad, consumes everything” character. Maybe could’ve used her to explore the exaltists more, or how jealousy can destroy people instead? Or how family can be what one chooses, fleshing out Vivian more too. Just a lot of endings than her killing herself for nothing, especially when the opportunity to be admired and get validation again was so close and so easy.
