Naruto could use his own growth and strength as an example. He shows Sasuke that he has become stronger not just in power but also in his understanding of the ninja world. He tells Sasuke that together they can change Konoha for the better, that Konoha has changed since he left and is now a place where he can be accepted and contribute. He might also share his own experiences of loneliness and how having Sasuke back would complete him in a way.
It could be the village elders. They often make decisions for the benefit of the village as they see it. They might think Naruto is needed back in Konoha to deal with potential threats or to boost the morale of the villagers.
One possible reason could be that they need his power. Naruto is extremely powerful, and Konoha might be facing a new threat that they believe only Naruto can help deal with. For example, a powerful enemy from outside the village might be on the verge of attacking, and Naruto's combat skills and unique jutsu are crucial for the village's defense.
One possible reason could be that Naruto is extremely powerful and his skills are needed to protect Konoha from a new and powerful threat. His combat abilities, like his Rasengan and Sage Mode, are crucial for the village's defense.
Naruto might initially be resistant. He could feel that Konoha is trying to control him again, just like in the past when he was often shunned. If he has found a new life or purpose outside of Konoha, he might not want to give it up easily.
One possible reason could be a new threat to Konoha that only Naruto has the power to face. For example, a powerful enemy has emerged and the village elders believe Naruto's strength is essential for the village's defense.
One possibility could be that Naruto and Sasuke, with their newfound understanding and power, decide to bridge the gap between Konoha and Suna. They might start by sharing their unique skills and knowledge. For example, Naruto could teach Suna ninjas about his shadow clone jutsu, while Sasuke could offer insights on advanced chakra control. This would lead to a stronger alliance between the two villages, with the two heroes becoming symbols of unity.
It's not clearly stated in the original Naruto series that Konoha as a whole watches Naruto vs Sasuke fanfiction. Fanfiction is a creation of the fans outside the official story. However, it would be an interesting concept to think about. Some characters might be amused or even inspired if they were to read such fan - created stories, but there's no in - canon evidence for it.
This type of fanfiction concept is really out of the ordinary. Naruto's character is built on his values of friendship, loyalty, and his dream of becoming Hokage. Killing Sasuke would mean betraying all of that. However, in a fanfiction, the author might be exploring the 'what - if' scenario. For example, what if Sasuke's actions against Konoha were so heinous that Naruto felt he had no choice? But still, it's a far - fetched and very different view from the original Naruto we know.
