I hate her soooooo much, I hope Kishi finishes her off before the end of the manga and I wouldn't care much for her dying, she was absolutely useless in battle. Sure she can heal, but so can many other people. She's strong? Not comparable to the current enemies in the manga. She has toxins/antidotes? Again, a lot of other people can do this and can do it better. She just stands by and even her own character is influenced by her absolute uselessness and she doesn't provide a very strong love interest for Naruto imo.
