if sasuke ever reaches nagatos level naruto is donr for because a fully powered nagato would kill naruto
and if u dont believe me consider this
he flattened for the most part the entire village and he had six bodies draining his chakra pool (noted that the fat one probably lessend the strain by absorbing chakra from whomever attacked him) but imagine nagato having all the chakra he used to waste the village in a fight with naruto (sgae mode extra clones frog summons whatever) and no hinata to bring about the six tails nauto would get absolutely wasted
in fact if pain had intended to kill him he could have already done so so if sasuke gets as powerful as pain its over for naruto
