I like her for the fact that she seems kind of like a comic book villainess. “I’m kidnapping your queen, and oh, by the way, I planyed bombs around the city. Have fun.” That made me laugh pretty hard, more than I can say for some of the others you encounter.
As for finally killing her, I doubt it. From her back story she “saw” the future for her people and grand plan for them. I feel like she’ll be around for awhile till she gets the ball rolling on whatever that was.
