Considering others just soloed all of your arguments I don't really have to I guess. Sasuke in no shape of form had to push himself to get Itachi's eyes, he simply could have transplanted them after Itachi let him win their fight but chose not to and instead let his hatred consume him into fighting the kages. He over used his MS in like a week while Itachi had his for 9-10 years (Sasuke was like 6 when Itachi killed the Uchihas). Sasuke didn't need to fight the Kages, he chose too which was he's dumb hate made him do where as Hebi Sasuke wasn't blinded by that hatred and would have waited for Danzo to head back to Konoha then attack him. Hebi Sasuke>MS Sasuke in terms of strategies and smarts.People forget that Sasuke had to push himself to get Itachi eyes. Itachi would not have give him his eyes willingly. Thus Sasuke Power up was earned!
Unlike other people in the series who get the second strongest chakra pool in the series for free. Get a free place to live.. Free education.. Free scroll full of kage level jutsu.. Free powerup everytime they lose Or the free ability to sense and mix sage chakra. or the free ability to TNJ and PNJ my way out of everything
I guess you can say being tricked into stealing the forbidden scroll is free if you want but he only learned Shadow clones and says that in chapter 1. Naruto actually had to train to learn and master SM, show me scans of Sasuke training to learn to manipulate Amaterasu in enton or where he learned to use Susanoo, fact is he just happens to unleash Susanoo more and more in fights wasn't free powerups? He did no training for it, it just came in battle yet you argue about BSM? Naruto already show to start training in KM and already trained in SM and even fused them way back so it wasn't like that powrup wasn't foreshadowed by Kishi. Naruto used his training of SM and applied it to BM, not that hard to understand. As for TNJ, What is TNJ? You can say it's a type of Manipulation. Orochimaru manipulation Sasuke, Kabuto, sound 4, and many more, Tobi did to Sasuke, Itachi (in some expects, made a deal for Itachi to join and he won't touch Konoha but still gain Itachi and sent Kakuza and Hidan to Konoha anyways), Nagato, Kisame, Minato (In a way, he wanted Minato out the picture and that happened), Itachi did to Sasuke. They all TNJ other people.
No he didn't, to work to gain access to it is to have knowledge of it so you can work at it unless you're being prep for it by someone eye. Itachi planned out their fight and one of his goals was to push Sasuke to his limits so he can remove Orochimaru and the CM from Sasuke and the other was to die by Sasuke's hands so Sasuke can awaken the MS by killing someone close to him. As for the EMS, it was right there, all Sasuke had to do was take it. He chose not to but instead let his hatred overcome him and attacked the Kage summit instead of waiting until Danzo was heading back to Konoha which is something Hebi Sasuke would have done.The point is he worked hard, & got a powerup.
He may not have wanted it but it was there, he did the work in order to gain access to the reward, accepting the reward is a completely different thing.
Enton wasn't a free powerup? Shape manipulation is not easy stuff, That's part of what the rasengan is which shown to be hard when Naruto was learning it. Sasuke traied to do it with his chidori but how can't he apply that to a complete different jutsu that is powered by the eyes?
Like when Sasuke put out Amaterasu, he didn't know he could but then after he did he tried doing it to Bee too and did. He didn't just do it without knowing, he saw Karin was on fire and wanted to put it out and it went out then he thought to himself that he actually did it.
Anyways it's dumb to discuss these, both Naruto and Sasuke's power up are tools that they have access too, it's about how they use those tools in battle. So far both still need to actually train/complete their training (Naruto started but never finished) before they both fight so we can have the best fight out of them.
