It also doesn't help that from any reader's point of view this strong bond has never been shown or developed.
Team 7 is formed, they do one mission as a squad, Naruto and Sasuke really never interact as friends, then the Chuunin Exam starts and Sasuke is unconscious or unavailable for most of it, basically never interacts as a friend with Naruto yet again, then seethes at Naruto for beating Gaara; when Itachi is back in town Sasuke is informed that he's going after Naruto and goes to him not to save him, but as a mean to meet Itachi; goes into a coma, as soon as he wakes up fights against Naruto 'cause he's angry that the village retard has become stronger than him, then gets "kidnapped" (he goes along), tells Sakura he doesn't give a fuck about her or Naruto, goes in a coma yet again, and finally Naruto reaches him and once again Sasuke tells him to fuck off, Naruto loses and Sasuke becomes rogue.
The Naruto that goes around in Part 2 is someone who basically made up this super strong brotherly bond with Sasuke that never existed from the reader's POV. At least the anime makes up some filler where they interact a little bit, but Kishimoto never wrote a single chapter dedicated to their friendship blossoming in any way that wasn't "he's stronger than me, I must train hard", which is even less than what Toriyama wrote for Piccolo or Vegeta in Dragon Ball
