Naruto was just a bi-product of the system. It’s all just a set up for Boruto. Sure, Naruto creates temporary peace, but with same ninja system, it won’t last forever. And as you can see in Boruto, the peace has ended and the cycle of hate has begun again. Kawaki wants to end the way of the ninja because his belief is like Kiro’s in the fact that the system is a failure in its self. The cycle will continue unless the system is changed. But that’s just a theory tho...BRUH ITS OK RAIKU IS OUR NARUTO
