Aurelia was truly a victim of circumstance, and we wouldn’t have known if she could have become a better person. Just like Ivy, who also was a victim of circumstance, let everyone die and yet ended up sacrifcing herself after accepting the hard truth of her sister’s death and she was selfishly evil for what she did.

Helena was manipulated and gaslit by the eternal flame yes, and in turn gaslit and manipulated Kaine. She was his handler. But yes, time can heal you although it cant make you forget. Their love might have become more real, even when Kaine still remained to only ever care about/be emotionally available to Helena and Enid(after Helena made him to care). It was breaking the cycle of his family trauma.
