One idea could be a story where Naruto and Sasuke have to team up with Karin to face a new, powerful enemy. Maybe they initially don't trust Karin completely, but as they go through battles together, they start to respect her abilities more and form a strong bond as a team.
A possible plot could be that Karin discovers a hidden power within herself that could either save or destroy the ninja world. Naruto and Sasuke, being two of the most powerful ninjas, are called upon to either help her control it or stop her if she goes rogue. This would create a complex dynamic between the three characters as they grapple with trust, power and their own personal beliefs.
In some Naruto fanfictions, Karin might succeed in seducing Sasuke. However, it really depends on the writer's take on the characters and the plot they've crafted. Some fanfic authors might want to explore a more romantic or complex relationship between them, while others may keep Sasuke completely focused on his revenge and not be swayed by Karin's attempts at all.
In the realm of fanfiction, almost any scenario is possible. Regarding Sasuke divorcing Sakura for Karin, it may exist. Fanfiction authors draw inspiration from the source material and then take it in new directions. The idea might stem from Karin's past feelings for Sasuke and some fans' desire to see how such a relationship shift would impact the characters. It could also be a way to explore the characters' personalities more deeply, for example, how Sakura would cope with such a betrayal and how Karin would handle being with Sasuke in that context.

Fanfiction just gives people the freedom to deviate from the original.
There could be. Fanfiction writers sometimes come up with very creative and sometimes controversial ideas. However, this particular plot would be quite a deviation from the original story's themes of loyalty and friendship. In the original, Sasuke has his own complex relationships that don't involve such unfaithful behavior in this way.
In Naruto fanfiction where Karin tries to seduce Sasuke, a prevalent theme is manipulation. Karin is often portrayed as a character who is not above using her femininity to manipulate Sasuke for her own ends. Another common theme is the exploration of Sasuke's character. How he responds to her seduction attempts can show different aspects of his personality, like his self - control or his susceptibility to emotional manipulation. Additionally, the theme of redemption can be present. Karin might be trying to seduce Sasuke as part of her own journey towards redemption or a change in her character.
One idea could be a story where Karin has to choose between her loyalty to Sasuke and her newfound friendship with Naruto. Maybe they are all on a mission together and face a powerful enemy that forces Karin to make this difficult decision.
