Right, I get that with wanting to bond with your brother. Hope that your kindness will change the ways of their heart and make them a good person too. That is understandable, with normal siblings.
These two from birth were in a deadlock of “who gets to keep the body.” Meaning that one trumps the other, or they somewhat fuse. Caliborn was aggressive from day one so the only way for Cali to exist was to meet in the middle and fuse.
I’m not saying that that wasn’t/isn’t necessary. Or that she couldn’t hope to be friends with her family again.
I am saying is that, when your own survival is on the line, it sort of throws a wrench in the “she just wants to reconcile.” Does she? Or did she see that being the only way for her to somewhat live?
Just, the idea of being “good” to get yourself to survive like that is a little manipulative and creepy to me. Not by much, just a little.
