Konoha could also try to rehabilitate Deidara in some fanfic ideas. They might see if they can turn him away from his violent and destructive ways. Maybe they'd assign some ninja with good persuasion skills to talk to him and make him see the error of his ways. They'd also keep him under strict surveillance during this process.
In certain fanfictions, Konoha might use Deidara's capture as a bargaining chip. They could try to exchange him with the Akatsuki for information or for the release of Konoha ninjas that the Akatsuki has captured. Or they might even try to get the Akatsuki to leave Konoha and its allies alone in exchange for Deidara.
It could also be a part of a larger plan. Perhaps the Akatsuki sent him on a mission that was actually a trap set by Konoha. Konoha could have leaked false information to lure Deidara in and then capture him. Another possibility is that he got separated from his Akatsuki partners during a fight in Konoha and was then overpowered and captured.
Konoha would initially be in shock. Naruto is a hero to many in the village, and his sudden departure with Itachi, who was once considered a traitor, would cause a lot of unrest. The villagers might start to question the leadership of the village, wondering why Naruto left and if there was something they could have done to prevent it.
Well, in some fanfictions, Naruto might outsmart Konoha by using his unique knowledge of the village's secrets that others don't know. For example, he could use his understanding of the old tunnels under Konoha to his advantage in a situation where he needs to escape or gain an upper hand in a conflict.
Maybe some of the more conservative village elders. They have always been a bit wary of Naruto because of the Nine - Tails inside him. So they might be behind his capture in the fanfiction.
Well, it would be a big loss for Konoha. Naruto is a powerful ninja, and his absence would mean one less strong fighter to defend the village. Ino, too, has her unique skills in mind - related jutsu and communication. Their departure might also lower the morale of other ninja, especially those who were friends with them or looked up to them.
Konoha might be in shock at first. They have always relied on Naruto to some extent, and his refusal to help is completely unexpected.
It could lead to political unrest in Konoha. There might be those who blame the village leadership for Naruto's departure. This could lead to power struggles as different factions try to take control and change the way the village is run. Some might demand more transparency and better treatment of their shinobi to prevent such a thing from happening again.
It could create a sense of unease and fear. Naruto is a very powerful ninja, and if he turns dark and leaves, the villagers would be worried about him coming back as an enemy. It might also lead to a decrease in morale among the ninjas who once considered Naruto a friend or ally.
On a more positive note, it could inspire some young ninja to step up. They would see Naruto's departure as a challenge to prove themselves and fill the gap he left. His leaving could also make Konoha re - evaluate its relationship with its ninja and how to keep them satisfied and in the village.
In some fanfictions, Konoha may suffer due to powerful villains specifically targeting it. For example, a new and extremely strong dark ninja group could launch a surprise attack on Konoha, causing destruction and loss of lives among its shinobi. This could also lead to a breakdown in the village's infrastructure and a sense of fear and despair among the villagers.
