When Naruto meets Nagato after repelling Pain's attack on the Konoha Village, he is forced to admit to Nagato that he doesn't have an answer to how one can break the 'cycle of hatred' that plagues the shinobi world. Naruto is only able to promise Nagato that he will find a way to break the cycle, and he manages to change Nagato's perspective through his conviction.
But, does Naruto ever find an answer to how he can break the 'cycle of hatred'?
- He does bring around many others towards his perspective as the series progresses, notably Kurama and Sasuke. He may even have stopped the 'cycle of reincarnation' of Hagoromo's sons, Indra and Ashura, through his final battle with Sasuke. But, how does this answer the question of how the 'cycle of hatred' can be broken, if at all?
- While it is true that Black Zetsu has guided/manipulated the shinobi world for ages in order to serve his selfish needs, is the sealing of Black Zetsu (along with Kaguya) enough for the 'cycle of hatred' to have stopped? If so, how?
The 'cycle of hatred' is an essentially human problem, just raised through a fantastical story involving ninjas, chakra and mythical creatures. One doesn't really expect the author Masashi Kishimoto to "solve" such a problem in his manga. But any truly satisfactory answer found within the story should ideally also be an answer to the underlying human problem.
Notice that this is true for all the "partial/incomplete" answers found by Nagato, Hashirama, Madara, Sasuke, and Hagoromo. Regardless of whether one agrees or disagrees with any of their answers, it still makes them compelling. So, is there a "final" answer that is found by Naruto in the same vein?
