Well, in such a fanfiction, Naruto's lack of understanding of hatred might lead to him trying to befriend his enemies more easily. For example, he could approach Sasuke in a different way, not fully grasping why Sasuke is so consumed by hatred. This would change the dynamic between them and the overall plot as Naruto might try more radical ways to bring Sasuke back to the village.
Naruto might also face hatred by becoming stronger. He trains harder and shows his opponents that he is not someone to be underestimated. For instance, if a group of rogue ninjas hates him because they think he's too idealistic, he proves them wrong by defeating them in combat and showing that his ideals are what make him strong.
He could become more idealistic. Since he doesn't understand hatred, he might strive to create a world where everyone gets along without any grudges. This would make him a very different kind of hero compared to the Naruto in the original series.
In some fanfictions, Naruto might overcome the curse of hatred through his unwavering belief in friendship. His strong bonds with his friends like Sasuke, Sakura, etc., act as a counterforce. He uses the power of love and understanding that he has gained from his relationships to fight against the negative influence of the curse.
It can create a lot of tension. If Naruto hates Sakura, it changes the dynamic of their team. Their interactions become more strained and filled with conflict, which can drive the plot forward as they have to work together despite their feelings.
It's often shown as a very intense and consuming force. Characters filled with this power might have a dark aura around them in the fanfiction. Their eyes could glow with a menacing look, signifying the 'Power of Hatred' within.
Well, in the fanfiction, the sealed hatred could transform Naruto into a more complex character. He might start to question his own motives and actions more deeply. Since the hatred is sealed within him, he may feel like he's constantly at war with himself. This internal conflict could lead to him making different decisions than he would in the original story. He could become more hesitant in his actions, always considering the potential influence of the sealed hatred on his choices, which is a big departure from his more straightforward and impulsive nature in the main Naruto storyline.
It can create a lot of conflict. For example, he might start attacking the village or his former friends. This would lead to battles and power struggles. The other characters would then have to figure out how to deal with him, either by trying to reason with him or by using force to stop his rampage.
The fanfiction could develop this hatred through the introduction of new characters. These characters might feed Naruto false information about Minato and Kushina, making him question their motives and ultimately hate them. For example, a character who has a grudge against the Uzumaki family could manipulate Naruto.
It can simplify the plot. Without Naruto's internal struggle with hatred, he may make more rational decisions, which can speed up the resolution of conflicts in the story.
It can strengthen the NaruHina relationship. Since Naruto hates Sakura and Sasuke, he might turn more towards Hinata for emotional support. Hinata's presence becomes even more important to him. He realizes that Hinata is the one who truly cares about him, not like Sakura who is preoccupied with Sasuke.
