Her Characterization starts as awful bitch and only goes downhill from there. At the start she comes across as an untalented, yet condescending bitch with an unwarranted sense of Self-importance and an Obsession with Sasuke who constantly abuses Naruto, who, being a socially maladapted pariah, thinks is normal and is head over heels for her. Seriously, the amount of contempt she shows for this little boy who has done nothing to her is so extreme, that at a point where she is shit-talking about how he’s orphan, Sasuke, the ultimate adolescent Brooding edgelord, actually comes down off of his high-horse of arrogant, detached apathy, to tell her to shut the fuck up and stop being a bitch.
And she never gets better, or learns a single thing about empathy. In fact she actually gets worse as the series goes on! We later learn that she had actually burned bridges with her childhood best friend because they both had a crush on Sasuke, who neither of them had even talked to at that point. Later in Shippuden, after Sauce goes full blown traitor and has to be hunted downZ she incapacitates Her entire team, leaving them at the mercy of any enemies, just so she can get closer to Saucegay and not have to try and kill him.
And then, the shit icing in on the trash Cake that is her character, is shown when she tries to manipulate Naruto’s (thankfully at this time former) crush on her, to keep him from going after Saucegay, complete with crocodile tears and everything. And this was all After the girl who ACTUALLY liked that sperg almost just dies for him. Even Naruto, who’s first idea of friendship came from Mr. Bleeding edge and this bitch, told her she was full of shit and that she needed to stop lying to herself.
And the worst part is, she’s STILL considered one of the good guys after all this!
I’m not going to pretend Naruto is good, or even Okayish, but Sakura Haruno is without a doubt, the worst part about the show.
