One possible plot could be that Naruto is pushed over the edge by the constant betrayal he faces. For example, if the village he has always protected turns against him due to false accusations of being a threat. He might start using his powers in a more erratic and dangerous way, not caring about the consequences. This could lead to a showdown between him and his former friends who now see him as a menace.
One possibility could be that after facing too many dark magic encounters, Harry's mind starts to break. Maybe the constant threat from Voldemort and the losses he endures, like the death of his friends, push him over the edge. He could start to have hallucinations and lose his ability to distinguish between reality and dark magic-induced illusions.
One possible plot could be that Naruto is constantly ostracized by the villagers even after all he has done for them. The years of being treated as an outcast and having his good intentions misconstrued finally push him over the edge. He starts to see the villagers as the real enemy and decides to use his power not for their protection but to make them feel the pain he has endured.
Maybe in this fanfiction, Naruto is exposed to a powerful dark jutsu that slowly corrupts his mind. As he becomes insane, he begins to abandon the values he once held dear. He could start using his powers for self - gain rather than for the protection of the village, like taking over control of Konoha in a tyrannical way.
Maybe it could be due to the loss of his friends. For example, if Sasuke died in a battle and Naruto couldn't save him, the grief might push him over the edge and into insanity.
One possible plot could be that Naruto experiences repeated and extreme betrayals. For example, if his friends in Konoha turn on him due to false accusations of him being a threat. This would gradually chip away at his mental state, making him question his values and identity, and slowly drive him insane as he feels isolated and persecuted.
