Okay, some people believe that Naruto would've been much stronger if kurama wasn't there and not sealed inside him, because Minato would've been alive and thought him many techniques, he still would've learned sage mode and would've become stronger than how he is now. He sure would've become strong, but without Kurama, he would've been much weaker...
Maybe you think think that I'm thinking that because of his KM, his KM is very strong indeed.... but that's not his strongest power... his strongest power, the power he wouldn't have gained without Kurama, is his great will, his words... He has one of the biggest will right now, and that's very important and that is what makes him very strong right now... Naruto has the power to suck out the hatred of somebody (not easy), his words can convince so many people, just like with nagato..
When he was a kid, he had a lot of hatred stored inside him, so he knows how it feels... eventually his hatred "grew away".. this also made his will bigger, thanks to this he never stopped trying, he never gave up...
And because he knows how it feels to have a lot of hatred stored inside you, and how to handle it, he is able to remove the hatred of other people, and convince them... he even did that with the bijuu's
And all the hate he had stored inside him, was because he had Kurama sealed inside him, so nobody wanted to acknowledge him... but eventually everything changed... So Kurama was and is very important... (was:the hatred, will shizz) (is:KM)
Do you agree, or not?
