Hmm.. I see a lot of hate coming from people towards Sasuke. I'll say this right now, it isn't fair and here is why.
Let's compare Sasuke with Naruto since the beginning of the story.
Sasuke - He is a genius that only come once in a generation as many shinobi's of Naruto-world has mentioned.. All of his jutsu are cool-looking and he likes to act cool all the time. Oh yea, he also has Uchiha blood.
Naruto - hot headed and always rushing into things. We've only seen him victorious only when he started using his brain. But being the main character, Kishimoto made him as a clumsy, loud, and hard to predict shinobi.
They both studied under the same master when they were young (Kakashi) and they both studied under the legendary sannin in shippuuden. Naruto / Jiraiya and Sasuke / Orochimaru.
Each of them gain powers in their own way.. Especially Sasuke.
Let's start with Sasuke first. Ever since the Uchiha massacre Sasuke has always wanting more power for his path of revenge. However, if you pay attention in the manga, you'll notice that Itachi told Sasuke that only if he gained the same eyes as him he will only be able to match him.
How do you gain the Mangekyo Sharingan? Easy, kill Naruto.. which Sasuke did NOT do. After he injured Naruto at the Valley of the End, he specifically said "I will gain power in my own ways!" and went off to train with Orochimaru in hopes of POWER.
Now for Naruto, you'll notice that he didn't care too much about being a smart and talented shinobi but that is what his character is. When Jiraiya found Naruto, he taught him a lot of stuff.. especially to give up on Sasuke (just as Jiraiya did with Orochimaru) and that he would remain dumb for the rest of his life. Naruto however, replied that he will stay dumb forever in order to bring his friends back.
Itachi also had a conversation with Naruto asking why he cared so much about Sasuke. In return, he was given an "unknown" power.
As the story progress, the two have been growing stronger and stronger:
Sasuke absorbed Orochimaru
Sasuke killed Diedara
This is the power of Sasuke without the Mangekyo Sharingan. Itachi mentioned that Sasuke has gotten VERY strong without the Mangekyo Sharingan and in return he was given a gift from Itachi in which he could've got from killing Naruto at the valley of the end. In a way, I believe Sasuke deserves to be where he is right now.
Naruto on the other hand, pulls out an amazing power ups too. Those of you shouldn't give up on Naruto yet just because you've seen what Sasuke can do.
Remember, Sage Naruto beat Pain but the real battle came into conclusion Naruto changed Nagato's mind about peace. Konan said to stop whatever he is thinking and just finish off Naruto, but Nagato instead uses his remaining chakra to REVIVE the dead instead of capturing Naruto.
Even after all that. Zetzu said to Madara (with team Hawk there) "Naruto has gotten very strong, probably stronger than Sasuke"
So now the Manga has switched to Sasuke story and we finally see his power, where it's almost equivalent to Naruto... or should I say Naruto is stronger?... who knows.
Let's be real here, Naruto has a gift that Sasuke doesn't have... and that is the way to "change people's mind"
First off, I don't really see the point in saying Sasuke is so strong he's gonna take out the 5 kage. He didn't kill any body other than the Samurai. If he has killed all the Kages then yes, we would question Kishimoto of why he was so powerful.. Correct?
In a way, Sasuke DESERVES to be where he is right now because he needs to be alive.
As Gaara would say... "What would you do in this situation.. Naruto?"
This is the fun I've been waiting for so I'm gonna give a thumbs up for this chapter because we know that nobody else can take care of Sasuke other than our only SUPER LOUD and UNPREDICTABLE NINJA - NARUTO!
P.S. Oh yea the hanging upside down staring at Danzo was the shit.
