The thing with Sakura and Naruto is that Kishi or more like Yahagi (That's his name, right? I ask because I remember a couple of times I wrote Yahanagi in the past lol ) really wanted to show that one should always save their friends no matter how far they're gone.
Problem was this has gotten to the extreme and beyond it, to the point of insanity. He should've had a limit to it, which unfortunately was never implemented.
It's gotten to the point in which Sasuke can do anything to anyone, and Naruto and Sakura would not only be perfectly fine with it, but also defend him. Especially true with Naruto.
Yep, what seems to have been forgotten is that sometimes death IS the only way to "save" someone. Sasuke had shown time and again (before all the magic, out of nowhere character pivoting) that he wasn't going to stop and had no desire to change. He constantly needed vengeance (and most of his actions stemmed from that; leaving Konoha for Orochimaru, "killing" Orochimaru, joining "Madara", abandoning Jugo and Suigetsu after the Kage Summit, nearly killing Karin, etc.) and once the current target of his vengeance was gone, he simply shifted the target to something else while making any excuse to justify it; first Itachi, then Danzo, then Konoha, and even if he succeeded in destroying Konoha, what next?
Oh yeah, Naruto totally never loved Sakura.
Hmmm....I don't seem to see Hinata with any connection, much less any hearts...
