Honestly Naruto isn't my favorite character though I do like his personality, the way he is, and most of all his optimism.....My favorite character honestly is gotta be Kakashi or Shikamaru......That being said I think Naruto is a huge success though everything he has he had some slight assistance he still EARNED it......Most things he has done were failed by MANY people before him......He has also done thing people could only imagine including Minato, and he will continue to do it......We've seen many chapters and many episodes where Naruto was training hard to accomplish what he has.....If anyone is a failure it's Sasuke.....Partically because he hasn't work for anything he has other then Chidori, EVERYTHING has been given to him.......He gets an eye transplant and it gives him all the power he's ever needed.....Honestly his eyes have given him all the power he's obtained (Minus the training with Oro)......But the biggest reason is that his pride and ignorance won't allow him to see what his brother really wants, it's something Naruto is desperately trying to obtain......Peace.....Instead, in spite of his brother that gave his ENTIRE life away for Sasuke he seeks only revenge.......He acts like no one cares about him when Naruto has gone to the end of the world and back 1,000,000 times for him.....I believe Sasuke, if anyone is the failure.....Though I actually do like Sasuke.....Ha
