There's no reason to hate Sarita, she's a really nice character with a big heart. I don't think she "stole" anything from Kenny but rather, she was a substitute. So instead of feeling completely heart-broken by Katjaa and Duck's death Kenny had someone he cared about and could confide in and even with Sarita in his life he still thought about Katjaa and Duck. I think that while Sarita was alive Kenny had a reason to be happy but after her death he lost it...if anything TellTale is to blame/dislike for that, not Sarita. I was really sad she had to die because 1. she was an amazing/lovely character in my opinion and 2. I knew Kenny would completely lose it after this. Like someone else said above, Kenny could have had a family again with AJ, Clem and Sarita as one happy family but instead he's made to look bad, angry, broken etc, which is really unfair if you ask me.
