The rest of his friends would probably gather around him, offering support and trying to cheer him up. They'd bring him water or whatever they thought might make him feel better. They'd also share stories to distract him from the pain, like the time they had an adventure together and overcame a difficult obstacle.
Naruto would be devastated. He might blame himself for not being able to protect his son. Sasuke would be angry and would likely go on a hunt for the perpetrator. His friends like Sarada and Mitsuki would be heartbroken. Sarada might vow to become stronger to prevent such a tragedy from happening again.
Well, if Boruto joins Akatsuki in a fanfic, it would be a huge shock to the Naruto universe. Boruto is from a new generation and Akatsuki was the main antagonist group in Naruto's time. He might bring new skills and a different perspective to the Akatsuki. Maybe he could try to change the Akatsuki from within, or he might be forced to do their bidding against his will at first. It could lead to some really interesting storylines, like how the existing Akatsuki members would react to this new young recruit.
Another concept is the Akatsuki's relationship with the new generation in Boruto. They might try to recruit some of the young and powerful ninjas. This could lead to a conflict within the new generation, as some might be tempted by the Akatsuki's power and ideals, while others firmly oppose them.
It could be a resurrected Orochimaru. He has always had an interest in power and the Akatsuki. He might return, more powerful than ever, and take control of the Akatsuki in the Boruto era, using them to carry out his evil plans, like creating an army of super - ninjas using some dark jutsu.
Boruto's reaction would be complex. He'd be heartbroken, for sure. He might start to question his own worth and purpose. But over time, he'd realize that he has to carry on Naruto's legacy. He'd become more serious and focused. He'd also become more empathetic towards others, understanding the weight of sacrifice. He might even start to study Naruto's techniques and leadership style more closely, trying to emulate the things that made Naruto such a great Hokage and hero.
Well, initially his friends in Konoha would be horrified. Naruto has always been a symbol of hope for Konoha. But if he became the Akatsuki leader in a fanfiction, they would start to question everything. However, as time passes, they might start to see the positive changes Naruto is trying to bring to the Akatsuki. For instance, if Naruto is using his godlike powers to stop the Akatsuki from their more evil plans and instead make them a force for good, his friends might gradually come around. But it would be a long and difficult process, filled with a lot of mistrust and misunderstandings at first.
They might change the course of history. For example, they could prevent some tragic events that happened in the past, which would then have a huge impact on the present and future they came from. Maybe they'd also meet their ancestors and learn a great deal about their family's past.
Well, Naruto would be in a really tough spot. He loves his family and the village, and this situation would be a huge blow to his traditional values. He might struggle to understand how this happened between his son and Hinata. Hinata's family, on the other hand, would be protective of her. Her father would want to ensure that Boruto is taking responsibility. Boruto's friends would also be surprised. Some might be supportive, like Shikadai, who would try to see the good in the situation, while others might distance themselves at first, not sure how to handle this new and rather strange development.
