Naruto could also experience a period of self - discovery. Away from Konoha, he may find new friends and allies. He might learn more about his own powers and his true identity, which could lead to a transformation in his character and abilities.
He might also become angry. Naruto has a strong will, and after the initial shock and sadness, he could turn his feelings into determination. He may decide to prove Konoha wrong and show them that he can be great without their support.
At first, Naruto is likely to be heartbroken. Konoha has been his home, and he has always longed for acceptance from the villagers. So being abandoned would be a huge blow to him.
One possible reason could be fear. Naruto has the Nine - Tails within him, and some in Konoha might be too afraid of its power getting out of control. They may not fully trust Naruto to keep it in check.
One possible reason could be that Naruto discovers some dark secrets about the village leadership that go against his values. For example, if he finds out that they have been using underhanded means to maintain power.
Naruto would be devastated. He sees Kakashi as a mentor and father figure. He might initially go into denial, not believing that Kakashi would actually abandon him.
One possible reason could be feeling betrayed by the village leaders. Maybe they made decisions that Naruto strongly disagreed with, like how they treated certain groups or individuals. If Naruto felt that Konoha was no longer the place that stood for justice and fairness as he once believed, he might abandon it.
He could become very determined to find out why Sakura left and try to win her back. Naruto is known for his perseverance, and he wouldn't give up easily on his family. He might also start to question his own actions and wonder if he could have done something differently to prevent this.
He would probably be very angry. Naruto has always been a free - spirited person, and being experimented on against his will would be a huge violation of his rights. He might initially try to resist physically, but as the situation gets more complex, he could start to plot his escape and revenge.
Naruto might initially be in shock. He has always counted on Kushina's love, and this sudden abandonment would be a huge blow. He could become withdrawn and quiet, not understanding why his mother would do such a thing.
Naruto would probably be conflicted. On one hand, he has a deep love for Konoha, his home. But on the other hand, he might have been hurt by the past events that led to his departure. He could initially be hesitant, but eventually be swayed by the thought of seeing his friends again.
As for Kakashi, he would be in a difficult position. He has mentored Naruto and also has a strong loyalty to Konoha. He might try to understand Naruto's reasons while also having to deal with the village's reaction. Their relationship could become strained as Kakashi tries to balance his duties to the village and his connection with Naruto.
Naruto would likely be extremely hurt. He has always considered the Konoha 11 as his friends and comrades. So, at first, he would probably be in denial, trying to figure out what went wrong. He might try to talk to them, to understand their reasons.
