Sakura's biggest wall and obstacle is only one, that is Sasuke. When human become so obsess with something they tend to forget about the most important things in their lives. Sakura is too obsess with Sasuke, we all know that whenever she hear his name, remembering him, or meet him, she instantly transform into different person. She believe she loves sasuke, but in fact she is obsess with him. Love and Obsession is different, when you obsess you want to possess or have that person for your own no matter what, but when you love you are willing to give up your happiness for someone. Remember what itachi said to naruto, never do things alone, always trust your friends, your father Minato was able to become hokage because he has your mother support Kushina, when sakura try to kill sasuke she wants to do it alone she thinks she don't want to burden the other especially naruto, THATS A LIE. She still obsess with him, thats why she can't do it. She poison Kiba, Lee, and Sai. Why she do that? She well know that sasuke is powerful she will never beat him alone. All she has done is reduce the chance of killing him by going alone, have you ever wonder why? Remember that itachi's word i mention above, NEVER do things alone trust your comrade or you will END UP LIKE MADARA. So you know that sakura NEVER trust her comrade regarding about sasuke, and she still obsess with him. Thats why she can't kill Sasuke, not even hurt him.
I believe sakura is the type of girl that really needs a slap on her face, a hard one, to snap her out of it, even now i'm still waiting for that. She needs someone to questions her about her love for sasuke. If we take out kishimoto out of the picture yes i have admit it that i really kittening hate her, she is the worst heroine i ever seen in the anime world. But i also believe she still HAS a chance, i believe she just in the darkness, SOMEONE NEED TO QUESTION HER LOVE TO SASUKE, then she will realize and she will ask that questions herself, "Now that you ask it why did i love him?". The best answer she got is the BENCH SCENE thats it. She will either look down and sad or she will remember and answer with the bench scene.
Edit:
Sakura is still young back there she doesn't really know herself what is love feels like, because she is young she assume herself that what she feels for sasuke is love, remember kushina herself said it to naruto that back there she was still young and didn't understand anything thats why she thinks minato is unreliable and looks weak.

Remember this panel? the very first real battle in this series, sakura was asking herself when she looks at how cool that idiot naruto at that moment, "This is naruto.... what's this feeling?" . THAT IS THE SEED OF LOVE MY DEAR SAKURA. But too bad you still young back there so you don't understand that vibe. That is the first vibe of love in first sight.
From that point sakura found comfort and can always be herself, express herself to the fullest whenever naruto is around her.

You think a girl can say something like that LOUD AND CLEAR to the person she want to impress? You NEVER want to tell something embarashing like that to the person you love. Imagine if naruto is not there, you think sakura will tell all of that to sasuke??
Whenever sasuke say something sakura instantly agree even though the inner self of her says different.

She just submissive around sasuke, its like she wear a mask, she can't be her true self. She wants sasuke to notice that she will always support him no matter what. Even though she knows that deep down shes not like that, this is not what she wanna be. And eventually this is become a real habit. She herself not aware of it but up till now until the end of that gaiden, she still wear that mask.
I could go on and blabbering, talking/typing forever but i don't wanna see you guys hating on her. She's not the one to blame... please do not hate her. The author just never let her to do the right thing.
In my conclusion she is smart, more than sasuke or naruto. Shes just need someone to snap her out of it OR tell her the truth about the bench scene, Those 2 are the key factor to saving her from this kitten that happening in the gaiden. Ofc its not gonna pull her out of the kitten hole shes already in, but at least reduce the damage.
