The Uchiha might initially be filled with anger. Their trust in Naruto, if it was there before, would be completely shattered. They could start to plot revenge against Naruto, believing that he has wronged them. This could lead to a lot of tense moments in the fanfiction as the Uchiha gather their strength and resources.
Some Uchiha might be suspicious of her at first. After all, she's an outsider. But others may be curious about her skills, especially if they know she's a strong ninja from her own village. They could either welcome her with open arms if they see potential benefits from her visit, or keep her at a distance if they fear she might bring trouble.
One possible reason could be a misunderstanding. Maybe Naruto is forced into a situation where he has to take actions that seem like a betrayal to the Uchiha. For example, if there are political forces at play that make Naruto choose between the safety of the village as a whole and the specific interests of the Uchiha clan. Naruto, being a firm believer in the village's unity, might make a choice that the Uchiha perceive as betrayal.
He could also feel angry. After all, he has fought for his friends and the village. To be betrayed by someone like Sirzechs would make him want to prove his innocence. He might start training even harder to show that he is not the bad guy Sirzechs is making him out to be. And he would likely try to find evidence to clear his name.
Naruto would be extremely hurt. He's a very emotional person who values friendship deeply. He'd probably first try to understand why Yugao did it. He might be in denial at first, thinking it's some kind of misunderstanding.
Naruto would be determined to get to the bottom of it. He would not just accept the betrayal at face value. He would use his skills and the help of his friends to investigate what made Jiraiya turn against him. Naruto's ninja way is about never giving up, and this situation would be no different. He would fight against this betrayal, both physically if Jiraiya became an enemy in combat, and emotionally, trying to understand the reasons behind it all while still holding on to the hope that Jiraiya could be redeemed.
Naruto would probably be extremely hurt. He has always looked up to the Sandaime as a grandfather figure. So, he might initially go into a state of shock and disbelief.
Naruto would probably be extremely hurt. He has always looked up to Sarutobi as a leader and a father figure. His first reaction might be disbelief, unable to accept that Sarutobi would do such a thing. Then he would likely feel a great sense of anger and betrayal. He might lash out and try to prove his innocence.
Initially, Naruto would be heartbroken. His friends and his village mean everything to him, and the thought that the gods, who are supposed to be just, have turned against him would be a huge blow. However, he wouldn't give up. He would use his determination and his unwavering belief in himself. He might start looking for allies among those who are also disillusioned with the gods or who believe in his innocence.
If Naruto saved the Uchiha clan, the story of the Hidden Leaf Village would be rewritten. The history of the Uchiha's massacre would no longer be a dark stain on the village's past. The Uchiha would contribute their unique skills and abilities to the village's development. For example, their Sharingan abilities could be used for better security or in battles against common enemies. There would also be a change in the relationships between characters. People who were once enemies of the Uchiha might have to learn to work with them.
Naruto would probably be extremely hurt at first. He values friendship and loyalty a great deal, so Anko's betrayal would be a huge blow. But he wouldn't give up. He'd likely try to talk to Anko to find out why she did it, hoping to change her mind.
