I mean I just don't see her appeal anymore I feel like she's at her best when she's Joker's side kick and I don't like the idea of her being made into a hero if what I've heard is true. I feel maybe it would be more fitting if her love for Joker got her killed like in the animated series where Batman says "I hope your still laughing when the joke's on you." I just feel Joker killing her is the most logical direction to take her character and I'd prefer her obsession/love for Joker to be her end making her a cautionary tale.

Something like this scene for example
