In fact, Sasuke and his derivative backgrounds in the current "Naruto" are already very noisy in the plot. Maybe Naruto's first part wants to tell the story of Naruto, but as the manga plot gradually progresses to the Shippuden period, the main line of Naruto is actually the blood and tears of the Uchiha family, and the character of Sasuke is the epitome of Uchiha.
Naruto's story has a problem that I personally think is very serious, that is, under the theme of the struggle and growth of teenagers, there is a lack of many independent phased tasks, and even his task chain is given by Sasuke, that is, to bring his good brother who "went astray" back on track, and as for his realization of the ideal story ending, it is a by-product of various events encountered in the process. In other words, in the vernacular, he didn't drive the plot forward, but the plot took him away. Sasuke's story, on the other hand, has a very strong motivation for the characters, and a clear goal for the audience can be seen, which is revenge for his brother killing his parents.
Such a character background naturally contains strong emotional conflicts, and in addition to depicting the growth and trials experienced by the characters, a lot of puzzle-solving plots can be added to create reversals to enhance the drama of the plot, and even extend the worldview of the work. (In fact, the author did just that, adding reversals, expanding the world view, etc., but Itachi, who is a key character in Sasuke's story and a stage boss, was washed ashore by changing the character design in a stiff way, which affected the development of the whole story, resulting in a complete collapse of the protagonist and the logic of the plot) But in the if with Sasuke as the protagonist, after completing the revenge, does his story have to stop?
Actually, it's not, because according to the plot direction of the original work, Sasuke can get more information through the stage boss Itachi, that is, there will be a stronger enemy in the near future that he must face, and the background story of this enemy is also closely related to himself and the ninja world, representing the history of the Uchiha family and ninjas. As a result, the protagonist in the next stage will still be full of subjective motivation to become stronger and understand the world. Going back to the original book, we can find that almost all the key plots in the Naruto story have the Uchiha clan.
This in itself is enough evidence that Sasuke is also suitable as the first protagonist, as these intense conflicts surround him for legitimate reasons, so he is the most suitable character to be the focal point in his own right. Judging from the tension of the work and my personal perception, it is the story of a hot-blooded teenager with a special identity who was neglected and discriminated against, but in the end, he was recognized by everyone for his hard work and will, and grew into a strong man who guarded world peace.
The latter may be more malleable, starting with a young man with a blood feud and completing his revenge at any cost, and ending with a battle between the ancestors and the last of the clan over the battle of ideas. (Although Naruto's theory of effort collapsed into a bloodline theory in the original book, Sasuke and Madara did not carry out any advanced **, but it does not prevent the core of the work from being like this, so I compared it with their respective ideal states).
Looking at the Hokage, although Sasuke ostensibly wants to kill this and that, but in fact, no one is harmed, but he has made more credit than Naruto, and Naruto's main goal is to chase Sasuke, and other credits are still incidental, so there is really no problem in giving the Hokage to Sasuke, except for the identity of Konoha traitor, there is nothing else to black, think about it carefully, the few people Sasuke killed are either traitors or villains, not a decent character has never been killed, and when practicing under Orochimaru, he does not kill and capture. Isn't this a tsundere protagonist?
Naruto seems a little idealistic, but Sasuke's idea I don't think it's realistic, because he also can't solve these problems, he just focuses the contradictions on himself temporarily, but Churchill is right, there are no permanent friends, only eternal interests, and when the common enemy disappears, the original contradictions between the two countries will appear. I don't think what Naruto is doing can be to keep peace forever, let alone really trust the countries completely, but he seems to have made himself the link between the countries, the countries may not trust Konoha but believe in Naruto, Naruto may not be so political, but he is a spiritual leader.
