If Tobi was stopped and Itachi never did what he did, Civil War would have broken out(That was the purpose of the Massacre to prevent the Coup and Civil War), and the Uchiha may have actually succeeded in destroying Konoha and as a result Killing Naruto.I mightve open a can of worms here.
they do have a point when they bring up the massacre and kurama ordeal making them stronger but I'd also like to think about the other route.
Thats why I brought this thread up in the 1st place.
So as stated before, Tobi was stopped right there and then and Itachi never massacred anybody and everything is great. The hate on the village and Uchiha had finally subsided.
So, youd have Naruto with no Kurama to hold him back and get him killed as much as possible. Naruto would have his parents and obviously be beloved by all since hes the son of the hokage.
Itachi wouldnt have turned rogue and be there for Sasuke. Sasuke would probably be taken under Itachi's wing in some point.
So I dont really think taking out the massacre/kurama out of the equation makes them less stronger than what they were at that point. Id say they might even be better off.
They probably have more arsenal to defeat Pein.
Certainly Naruto would ( possible that he wont have Shadow Clones) also Team 7 wouldnt have split up in the first place.
At best, wed probably see a Sarada-Boruto kind of relationship going on with those two.
If Naruto beat almost all the paths of Pein just by his OWN power, imagine when he isnt spamming only 2 techs and has Sasuke as back up (pressumably under Itachi's tutelage)
Say, that the Uchiha's got some sort of dementia and forgot about how Konoha treated them and decided to forfeit the Coup and Naruto lived a normal life, from that point on, all we could do is speculate as to how strong Naruto would become and if it would be better for him.
