In defense of Katara

I'd quickly like to remind you all that parentification is a form of abuse that can leave mental scars on a child. I'd also like to remind you Katara's mom died to protect her, meaning she must have tremendous survivor's guilt. And finally, I'd like to remind you that when Katara lashed out at Soka, she was irrational, emotional and unstable, to the point of later using blood bending.

Edit: forgot to mention, Katara haired Sokka say he no longer remembers their mother's face.
