If naruto dies I think it would make the manga better then sasuke will be mad and kick some @ss and be hokage in a couple years, and where is kohanhamru? He is strong, well stronger then some of the k11 and is like naruto plus want him to see the 3rd.
Hashirama
Tobirama
Obito[technically caused his demise]
Tsunade
Onooki
Mei
Ay
Gaara
5 of the 8 he beat in a weaker state simultaneously. sasuke did not do so well against the 5 kage so what makes you think he could take madara solo? i didnt expect anything else to happen
