She didn't even "change" for the right reasons. It was only after the Rumbling started and she realized her loved ones were going to die. It was only after SHE was about to become a victim that she wanted to start playing nice with the protagonists. No other reason she turned.

As for Kaya, I still don't understand why Yams made her instantly forgive Gabi, I really hope she wasn't as weak or spineless as Mr. Braus was, but I do have to question why she would just suddenly forgive her sister's killer when she had absolutely no reason to. Forgiving someone who doesn't deserve it is a major indicator of weakness. She realized soon after not being killed by them that she was wrong, her trying to convince herself that they were still her enemy later is a coping mechanism at best but ultimately one that was clearly fading out.

You just answered your own question there. You consider it weakness (note that’s your opinion not at all a fact) therefore any reason they could give you wouldn’t be satisfactory because you wouldn’t accept it and consider it as such. It’s not that you can’t understand it’s that you wouldn’t even if you were told.
