I feel like if Kishimoto let Sasuke have some culpability things would be a lot different, but it's very much that, as Nate said, there's this reflexive need to defend Sasuke from criticism. He has a horrible track record and look, characters have gone above and beyond for him. I could have maybe, maaaybe, maybe made peace with the fact that Sakura ended up with Sasuke if he was a genuinely changed man. Cop out? Yes, but given this journey of saving Sasuke cost Naruto an arm and lots of my time as a reader I could imagine during peace time he took on responsibility and was at least physically present.
Yet no, I have no idea what he's doing but a father he is not being. He's not changed any. He's still causing problems for characters and they're still not letting him go. Sakura won't move on from him until the story does. This is the next generation, post-resolution Naruto manga, and it still comes back to Sasuke's absence and people missing him--still comes back to the mystery surrounding his family.
I feel some sympathy for Sarada because she can obviously tell something's not right, and I'll feel better about her character if she's shown supporting the woman that has for all intents and purposes raised her. Maybe Sakura is under a genjutsu (which would be absolutely disgsuting) but to Sarada, that's her mother. That's the single-mother who raised her and as far as the lash out goes I don't think Sakura is physically abusive to her. I want to believe Sakura could at least be a good mother.
It's just so upsetting to see Sakura like this. In a way, I think we all knew as anti-SasuSaku fans that this was the expected outcome of their marriage, but to see it and to see her so down... and then to see people supporting Sasuke and fans on this very forum calling her useless because she's in this situation is just so disheartening. Nobody deserves to be in this complicated situation and it seems that Sakura just really can't catch a break. I want her to finally let go of Sasuke and it's so frustrating to know that this plot-point isn't going to be dealt with properly. It's just going to keep making Sakura look bad for the sake of Uchiha-drama.
To quote Sakura, "I'm tired of it."
