He could also try to dodge her attacks while still trying to reason with her. Naruto has a strong sense of loyalty and friendship, so he would likely be very reluctant to fight back against Sakura. He might keep asking her why she's doing this and try to get through to her emotional side.
If pushed to the limit, Naruto might use his powers defensively. But even then, he would be more focused on stopping Sakura without harming her. He might use his speed or clones to avoid her attacks and create some distance, all the while trying to figure out a way to snap her out of whatever state she's in that made her want to kill him.
In some cases, Naruto might try to reach out to the Sakura he knows deep down. He could try to remind her of their past together, their training, and their shared experiences. He believes that the real Sakura would never do this, so he tries to break through whatever is making her act this way.
Naruto could be a bit hesitant at first if the situation is really complex or dangerous. He might need to think about the implications and if he is truly capable of helping. But in the end, his loyalty to Sakura and their friendship would likely make him agree. He might say something like 'Sakura - chan, don't worry. I'll do whatever I can.'
Naruto might initially be shocked and confused. He has always considered Sasuke as a friend, so Sasuke's sudden attempt on his life would be a huge blow. He may try to talk to Sasuke first, to understand why he is doing this.
One possible reason could be a misunderstanding. Maybe she was misled by false information about Naruto being a threat to the village. Another reason might be that she was under some kind of mind control. In some fanfictions, dark magic or evil entities can take over a character's mind and make them act out of character.
Well, in the original storyline, Kushina loves Naruto deeply and would never try to kill him. In this fanfiction, it's a complete 180 - degree turn. Her character is made to be much darker, which is a huge deviation as she's portrayed as a loving and selfless mother in the original.
In many such fanfictions, the development could involve Naruto's friends being initially misled by Sakura's framing. However, as the story progresses, Naruto's true nature and his past good deeds start to make some of them doubt Sakura's accusations. For example, Shikamaru, being the intelligent one, might start to suspect that something is off and begin to investigate on his own.
Sakura can be quite emotional in these fanfics. She may cry when thinking about how she let Naruto go or when she faces difficulties in getting him back. But she also uses these emotions to fuel her determination. She'll often pour her heart out to Naruto when she finally gets the chance to talk to him.
Sakura might be hesitant. She could say that she needs time to think. She values Naruto as a friend and is suddenly faced with this new revelation, so she wants to be sure of her own feelings before giving an answer.
Naruto could respond with anger at first. He has given so much to the Leaf Village, and this betrayal would be like a slap in the face. However, his kind heart might also make him wonder if there is a misunderstanding. So, he could start by trying to communicate with the villagers he trusts. If that fails, he might leave the village for a while to get stronger and then come back to confront those who wronged him.
Naruto might be very forgiving right away. He has always had a big heart and cared deeply for Sakura, so he could just accept the apology with a big grin and say it's all in the past.
