.....sigh.... not another "if naruto wasnt given kurama" thread.......
If naruto wasnt given kurama, one must think WHY wasnt he given kurama. At the very MINIMUM, naruto would had a larger chakra pool, better chakra control, and wouldve been much happier(maybe stronger to)
It is VERY LIKELY that most events in naruto wouldve been quite different. Uchiha may not have been massacred.(meaning sasuke wouldve been happy, and might be weaker.) Minato may have been alive to teach naruto. Naruto would not have had all the near death experiances, because he wouldnt be hunted, and would likely not have done the same missions.
The fact is is that naruto without kurama, would make for an ENTIRELY DIFFERENT MANGA.
If not for itachis eyes though, your precious sasuke would be nothing but a blind fodder.
