I didn't liked how she liked to my boy Naruto. Even a naive, idealistic moron like him caught on her BS and actually he said he hated people that lied to themselves. She got Naruto that state that he actually hates a certain kind of people. That's how low he though of her at that moment.
She has a superiority complex, when she said she finally caught up with Naruto and Sasuke I was blown away, is like she lives in her own little world.
She gets has some rage problems, a short temper is a bad trait to have.
She relies way too much on Naruto, Naruto is just a boy, the weight she puts on his shoulder is staggering, like she blames him for going away and failing to bringing him back is his fault. Not to mention that she didn't even went to the mission to retrieve him.
The Sasuke stuff is just meh, she is not the first woman to do crazy things because she is in love with a bad egg.
The false confession wasn't Sakura's greatest moment, but I've never seen it as act of manipulation. I've always thought of it as a selfless act. Sakura, knowing that Naruto loves her and that his unrequited love and sense obligation to keep his promise caused him pain, wanted to free Naruto of both. Even if she didn't love him, she was willing to be with him because that's what he wanted. Naruto has always hated people that lie to themselves afaik, so I don't think that's accurate.
Sakura certainly does not have a superiority complex. If anything, she has inferiority complex because Naruto and Sasuke always make her feel shit for not being as good as them. WI don't think she meant that she caught up as in her being as powerful, but rather as her being close enough that she could stand by them and matter in a fight - which she has undoubtedly proven that she does. Sakura is no longer a liability that needs constant saving.
The temper thing is a trope as old anime itself and one that Kishimoto likes to use for a number of other female characters, namely Tsunade, Kushina, Karin and, to an extent, Mei. Do you dislike this quality in them too?
I don't know what you're referring to with last point. I'd like you to clarify on that if you don't mind.
