In some cases, Sasuke could be angry. He might see Naruto's request as a sign of weakness or as Naruto giving up too easily. He could lash out at Naruto, telling him to fight instead of asking for death. However, he would still be deeply troubled by the request and would probably struggle with it for a long time, constantly thinking about whether or not he should consider it.
The relationship would evolve from a deep friendship and comradeship to a romantic partnership. They would have to be more open with each other about their feelings. Sasuke might become more protective of Naruto in a different way, not just as a friend in battle but as a future life partner. Naruto would also be more likely to confide in Sasuke about his insecurities and hopes for the future. Their bond would be strengthened further as they face the challenges of being in a relationship in the ninja world, like dealing with the opinions of other ninjas and the political implications of their union.
Well, one possible plot could be that after years of fighting side by side and having a deep understanding of each other, Sasuke finally realizes his true feelings for Naruto are more than just friendship. He might plan a very private and special moment to pop the question. Naruto, being the open - hearted person he is, would be initially shocked but then consider it seriously as he also values Sasuke deeply.
It often changes the dynamic between Sasuke and Sakura. It can lead to a more romantic and emotional storyline, with them spending more time together and sharing tender moments.
The team dynamic would be completely shattered. Sakura would be devastated as Sasuke was someone she had strong feelings for. Kakashi too would feel responsible for not being able to protect Sasuke. This could lead to the team splitting up or at least going through a long period of internal turmoil and lack of cooperation. And it might also change the way the village views their team, perhaps with disappointment or a sense of loss.
Yes, there might be such fanfics out there. In the Naruto fandom, with a large number of fans creating various types of stories, it's possible that some would write a story where Naruto destroys Sasuke in a way that could be seen as Sasuke - bashing. However, these kinds of fanfics may not be in line with the overall spirit of the original work which focuses on their complex relationship and growth.
In this fanfic, Sasuke's character would change in terms of his cold exterior. He would soften up a great deal. He might start smiling more often, especially when he is around Sakura. His actions would also be more focused on pleasing her rather than just his own goals. For instance, he might accompany Sakura to the hospital where she works just to be with her, which is a big change from his usually self - centered nature.
Sasuke might become more protective. Since Sakura is a princess, he feels a stronger sense of duty to keep her safe, which changes his usually aloof demeanor.
Sasuke's character can also develop through his interactions in the new time period. If he travels to a time where he meets his family again, he could learn the value of family and love that he lost in his original timeline. He might become more empathetic and less isolated. He could also gain new skills or knowledge from the different time, which would further shape his character.
Sasuke might be in shock at first. He can't believe that Naruto is dying in his arms. He may feel a great sense of guilt, thinking that he could have done more to prevent it.
