It depends. Some parts of the fan community might be interested in exploring darker or more complex relationship dynamics in fanfiction, including the idea of an abusive relationship between Sasuke and Sakura. However, many fans also prefer to focus on positive and healthy portrayals of their relationship. So, it's not uniformly popular.
Well, not really. The main Naruto series shows Sasuke and Sakura having a relationship that is complex but not abusive. Most fans who love the couple want to see fanfictions that build on their canonical bond in a positive way. There are only a small subset of fans who might be into the idea of an abusive relationship fanfiction, but it doesn't represent the majority view in the fan community.
In general, it's not that popular. While there may be some out - there fanfictions exploring this concept, the overall Naruto fan base tends to lean towards fan works that are more in line with the positive development of Sasuke and Sakura's relationship as seen in the original story. There's a much larger demand for fanfictions that show their love growing in a healthy, mutual way rather than delving into an abusive relationship theme.
