Generally, fans have a mixed reaction. A large portion of fans who support the Sasusaku relationship feel betrayed or disgusted by such fanfictions. They feel that the characters have been misrepresented. On the other hand, a small group of fans might view it as a way to explore the limits of the characters and the Naruto universe. But overall, it is a very controversial topic within the Naruto fan community, with more fans leaning towards not accepting this kind of extreme deviation from the original story's character arcs.
Some fans are horrified. They love the characters as they are in the original series and any deviation that involves such a violent act against a main character like Sakura is unacceptable to them.
Well, a number of fans are divided. Some feel that the insults are a form of character assassination for Sasuke, as they view him as a more complex and redeemable character than one who would just randomly insult Sakura. Others, though, might see it as a way to explore the darker side of their relationship and how Sakura can grow from being insulted and become an even stronger character.
Fans have a wide range of reactions. There are those who are vehemently against it. They have a strong emotional investment in the Sasuke - Sakura relationship from the original series. Then there are others who are more open - minded. They see it as an interesting exploration of different relationship scenarios within the fanfiction world. These fans might engage in discussions about why the author chose to take such a route and what it means for the characters' development in the fanfic.
Some fans are really into it. They enjoy seeing different takes on the Naruto and Sasuke relationship. It gives a whole new dimension to their dynamic. However, some fans might be a bit put off as it goes against the more traditional view of their relationship in the original anime and manga.
Fans have different views, but generally, the idea of sakura x sasuke abusive fanfiction is not well - received. Some fans who are more into positive and healthy relationship portrayals in fan works would be turned off by it. However, there might be a small subset of fans who are interested in exploring darker or more controversial themes, but they are likely in the minority. Overall, it doesn't fit with the general positive image of the couple that most fans have in mind from the original anime and manga.
Fans generally have a negative reaction. The Naruto series has always promoted strong bonds of friendship, loyalty, and love. The idea of Sakura cheating on Naruto goes against these values. Many fans see it as an attempt to create unnecessary drama and a misrepresentation of the characters they have come to know and love. Some may even avoid reading such fanfictions altogether as it conflicts with their perception of the Naruto universe.
A lot of fans reject this type of fanfiction outright. They feel it disrespects the characters and the values of the original series. The 'Harry Potter' series is about love, friendship, and fighting against evil, and having Harry kill Hermione completely goes against those ideals.
A third group of fans might simply ignore it. They are so set on the original story and the positive portrayal of Sasuke and Sakura's relationship that they don't want to engage with any fanfic that goes against that. They might consider it a disrespect to the original creators' intentions for the characters.
There would be other fans who might be intrigued. They like to explore different 'what - if' scenarios in fanfiction. They would see it as a creative way to explore the characters in a new light, even if it goes against the canon. However, they would also be aware that it's just a fictional alternative and not the real Naruto story.
In some fanfictions, Sakura's reaction could be more complex. She might be hurt not just physically but also emotionally. This could lead her to question her relationship with Sasuke and might cause her to make some big decisions, like whether to continue trying to reach out to him or to cut him off completely.
