LOL damn, man! You bombard me with a wall of text.
Sorry. Writers write. It's what we do.

I've said in a previous post that for me what Sai explains about Sakura "saving Sasuke from darkness" is along the lines of Sakura's justification for being capable of killing someone she loves.
The reason Sakura goes to kill Sasuke is Naruto's safety, but it's still emotionally difficult to commit such an act against someone you have feelings for (which is what Naruto was arguing for). That's where Sai's explanation comes in.
Yes, I understand, but that wasn't my point. My point was that Sai's explanation was speculation on his part. We never saw Sakura think or act in a way that said, "I love Sasuke so much... and he's sinking so low... I must kill him for his own good -- because I love him so much!!" What we saw from her was the opposite -- that she was choosing to do it for Naruto and because of Naruto.
That part of Sai's explanation just never rang true for me. When it was released and I read it the first time, I had to go back over that part several times because it was the part of the confession scene that didn't make sense to me. Everything else worked, in context, but then at the end he tacks on that part and it only managed to cancel out what Sakura had actually chosen to do for Naruto.
By saying what he did the way he did, Sai made it sound as if Sakura's main and true motive was killing Sasuke for Sasuke's good because she loves him so much -- as if Sasuke was her focus and motivation for everything. It's the main element that casts the entire confession in a questionable light. It's the element that makes it seem as if the feelings for Naruto that she confessed were completely phony.
It would have been completely different if Sai had said, "Sasuke is going to be killed, one way or another, and Shikamaru sought permission from Team 7 first. Sakura knew you would never agree, so she chose to take the responsibility for Sasuke's death upon herself -- for your sake, Naruto."
THAT would have made sense. That would not have been speculation on Sai's part, and would have been supported by what he actually knew and that we as readers had been shown.
But apparently this is something that only bothers me. I realize there are other examples of this kind of stuff in the manga, but Sakura's confession -- and how it came across to Naruto and to readers -- was pretty important to have Sai be muddying the waters with explanations that put things in a different light.
Just my opinion, and now I will take my little red wagon and go home.

Basically Naruto won't accept Sakura's feelings (which may or may not be fake) because she still likes Sasuke. Well all she has to do is get over her love for Sasuke, well that's all well and good except the whole finale of the Kage Summit arc showed that she can't stop loving him no matter how hard she tries and on top of that she can't exactly return Naruto's love without the possibility of it sounding like bullsh** like the fake confession and even then she has to actually prove she's over Sasuke because Naruto seems to be adamant as f**k about it and is not going to budge
This is patently false. You are ignoring the events that have happened since Sakura's confession that disprove these assertions you continue to make.
