Yes, there are likely some fanfics out there with such a plot. Fanfiction is a creative space where authors explore different scenarios. However, it goes against the general narrative of the Naruto series where Naruto is more about saving Sasuke.

Yes, there might be such fanfics out there. Fanfic writers often explore alternative storylines, and this would be a very dark and unexpected twist to the original Naruto story. It goes against the strong bond and rivalry that Naruto and Sasuke have in the canon, but that's the allure of fanfiction - to see what could happen if things took a drastically different turn.
One possible motive could be power. In some fanfics, Sasuke might be driven by an insatiable thirst for power and see Naruto as an obstacle. Another could be revenge, perhaps believing Naruto has wronged him in some way in that alternate story. Or it could be a matter of being corrupted by dark forces, which make him turn against Naruto.
In Naruto fanfiction, the idea of Sasuke killing Naruto is not overly common but does exist in some darker or alternate universe scenarios. Some writers might explore this to show extreme character development or a drastic change in the story's direction. However, it goes against the core of the original series where their relationship is more about rivalry and ultimately friendship.
It could start with a rift between them that becomes unbridgeable. Sasuke might side with a group that Naruto is sworn to oppose. Their ideological differences grow to such an extent that they end up in a final battle. Naruto, with a heavy heart, kills Sasuke perhaps because Sasuke refuses to back down and his actions are endangering too many lives. This would be a tragic departure from the original story where their relationship was centered around mutual understanding and redemption.
There could be. Fanfiction allows for a wide range of interpretations and alternate storylines. But it's a really extreme and disturbing concept considering the bonds that Naruto, Sakura, and Sasuke share in the official story. It would be a very different take on the characters, and most fans who love the original story would probably find it hard to accept.
One possible motive could be a dark magic or mind - control situation. Maybe an enemy has the power to control Naruto's actions and forces him to kill Sasuke against his will. Another could be a miscommunication where Naruto believes Sasuke has done something unforgivable, like harming the village in a way that Naruto can't overlook.
Sasuke's development would be complex. He might start to question his entire ideology that led him to kill Naruto. He could become more empathetic towards others as a result of his regret, realizing the value of life that Naruto always represented. He might also try to make amends in the ninja world, but it would be a long and difficult journey as he has to deal with his own guilt.
If Sasuke kills Naruto and regrets it, it would completely shatter the hope that Naruto represents in the story. The ninja world, which was slowly moving towards unity because of Naruto, would plunge into chaos. Characters like Sakura would be deeply affected, and Sasuke himself would probably isolate himself even more. His regret might lead him on a new journey of redemption, but the damage to the world would be hard to undo.
