Yes, Kishi gave plenty of examples of Shinobi fighting other Shinobi, where there wasn't a clear-cut "good guys vs. bad guys", but simply opposing sides. That's what Jiraiya, Yondaime, Kakashi, Tsunade, and all the other adults in the Naruto universe had to struggle with. That's why people like Danzou and Raikage don't believe in childish, idealistic answers. That's why Nagato resorted to insane measures such as using ultimate terror to force people into living peacefully.
It was alluded to many times that Naruto would have to face this kind of hatred eventually, but it seems like that only means he's got to beat Sasuke. As far as winning the war goes, it's shallow. They just have to take down the army of bad guys, and the good guys win. It's so shallow compared to the other Great Ninja Wars we've seen clips from. It's not like I'm not interested in seeing the fights ahead, and whatnot, but that's all they are. Fights. There's no real ideal behind them, there's no passion. It's just mindless clones and zombies going up against "good guys." And these Zombies (most of whom committed suicide in some way or another to begin with!) are one-by-one turning good again and asking people to kill them. Figures.
Oh yeah, and these good guys were militarily opposed to one another in wars full of hatred and passion only decades ago. Funny how Naruto's "answer" was supposed to unite the Shinobi world and bring true peace, and they united so easily. Yeah, Gaara gave a cliche speech and made everything better. Yeah, they don't have much choice at the moment if they want to stop Madara. But am I really the only one who finds the direction this has gone to be a bit too shallow compared to what we were getting set up for? I mean, Madara is so blatantly evil, the manga's finally found an villain who WON'T be redeemed and commit suicide. Despite this, he's "take over the world" scheme just isn't a very interesting or compelling motive compared to Pain, Orochimaru, or even Sasuke (at least Sasuke just wants vengeance against everything, he's not some lame supervillain wannabe).
I wait impatiently every week for releases. I frequent these boards more often than I should. I love this manga. But on this issue, I feel I have to be a bit critical: the premise of this war just doesn't deliver. I still look forward to seeing how Naruto confronts hatred with Sasuke, and all, but when I see Kishi throwing around statements like "Now, for the first time, they will experience: War!" after all the hype Nagato gave us, and then see something as bland as Zetsu Clones getting steamrolled, I'm just not feeling the tension. How are the kids supposed to feel bad about "killing" evil plants or zombies? Yeah, they see their own comrades die, but the hatred they feel won't be directed at enemies who suffer the same pain, or feel fear/anxiety. It has no meaning in terms of the image of "war" Kishi built up so Painstakingly.
They're supposed to hesitate to land a killing blow. They're supposed to feel regret, or come to terms with "kill or be killed"... at this point, the "killing" taking place isn't real. Are Naruto and Sasuke really going to end this manga with only one kill each (the mutual killing of Madara when they inevitably team up)? Does that really give them credentials to preach to people like Nagato, Raikage, Danzou, and the rest of the hardened generations of Shinobi about what the solutions to dealing with hatred and loss really are?
Perhaps I'm looking at this the wrong way (and here's where some people will doubtlessly say "ya think???"). Perhaps Naruto's hands staying clean for this long is exactly what allows him to preach to hardened killers. Perhaps it's a sign that he's truly found a path to peace, even if he's clearly attempted to land killing blows on several Shinobi, and has only been saved from doing so by plot devices. Perhaps he's destined to slay zombies/vegetables for all eternity, and all the bad guys will off themselves so that the good guys remain positive role models for the teenagers who read this, and everyone can go to bed at night with happy visions of cartoon wars with no moral ambiguity. However, I had hoped for a more compelling depiction of war after the all the hype throughout the manga, and it seems Naruto's generation (and thus the audience) have gotten the shaft as far as "Great Ninja Wars" go.
