Do you know what development is? I don't say this as an insult, I'm actually asking. Where I'm going with that question is that if Karela doesn't like who she is or starts realizing that who she is isn't what she wants to be any longer, she can work to change that image over time. If you've been one way forever, it can often take time to completely turn that around into a more positive image for you and your character. If you develop her she can change, but I think the time for 'quick personality edits' is too late since her nature is already set in stone. You can work to change her now, if you want her to be different.
