I don't think there is a moral hypocrisy.
Really? It's a flagrant dismissal of an act of vengeance despite the practice being denounced by those who adhere to Naruto's ideology.
This concept that revenge ( but also the idea that you can fix everything by killing the enemy) is wrong is only kept by a select few individuals. Mainly Jiraya ( probably Minato) and Naruto. As for the others taking revenge is perceived as normal or at least tolerated.
This fails to address the fact that Kishi has been emphasizing the repercussions of revenge. Of course numerous characters within the manga refer to vengeance and hatred as acceptable practices but because of Naruto's philosophy being emphasized as the correct one, at least when relating the dilemma of people wishing to harm others for previous wrongdoings, to see someone criticize Sasuke's aspirations for vengeance whilst not applying that same standard to others is where the hypocrisy is engendered.
Also, since Gaara's speech to the alliance forces about putting aside their differences to act as a single united military, it appears that everyone is beginning to abide by the principals of forgiveness and compassion that Naruto carries.
The moment when Team 10 had it's desire for revenge, no one really opposed them. They came and helped Naruto included.
Tsunade was opposed to them leaving the village because she was able to comprehend that impudent gallantry would only result in their deaths. Just so they could quench their thirst for revenge. But once again, I already addressed this numerous times in my previous post. Also, you're forgetting that the most vocal dissident to revenge was present and he never expressed any personal grievances with Team 10 allowing those negative sentiments to cloud their sense of judgement or that they would be sacrificing the authority of their leaders just to try and locate a duo of Akatsuki members. How is that not hypocrisy if Kakashi was so adverse to someone seeking vengeance previously in P1? Or can we admit that there does exist inconsistent reactions in Kishi's manga that would make us question the validity of already established notions? At the very least he should acknowledge that their plans would likely not be sufficient enough to succeed since they are fighting against the most powerful organization of shinobi in the world excluding the Alliance.
But when Naruto decided not to kill Nagato, later some of the villagers ( not sure if it was Shukako or Inoichi) suggested not to waste time talking but to proceed on neutralizing the threat.
Yes, and whilst their logic may have have practicality in that Nagato may still present a threat to the village their judgement was incorrect to indiscriminately attack him without first acquiring information relating to his motivations. Then again, if Shikaku and Inoichi accompanied Naruto, would Nagato allow them to approach him? Could they restrain themselves from attacking him? Possibly not, but your point here is valid. They had yet to be influenced by Naruto's precepts but I refer to my answer two responces above this one to address this issue.
Shikamaru also speculated that Naruto may want to spare Sasuke and not kill him to resolve the crisis.
Was Shikamaru personally impacted by Sasuke's actions? Did Sasuke murder anyone whom Shikamaru was close to? No, in fact he openly admitted in P1 that he didn't know Sasuke very well but that since he was a fellow Konoha shinobi that he would fight to return him to the village. There were never any direct interactions or personalized suffering to coerce Shikamaru into wanting to kill Sasuke like with Kakuzu and Hidan. Their relationship was formal in nature.
The fourth Raikage assumed that his brother was dead and wanted Sasuke's head. And the entire village followed that wish.
Raikage and Kumogakure had a legitimate reason to pursue Sasuke that was unrelated to vengeance. He illegally encroached into their lands, assaulted one of their citizens, captured (presumably) their most vital military asset, and murdered a pursuing Kumo scout. All of these formal aggressions on top of the fact that Sasuke is technically a missing nin should make him a target if the regulations concerning missing nin are applied here.
Was there a personal motivation to Raikage's actions? Yes, of course there was. But he had sensible reasons to justify his pursuit of Sasuke as well.
What team 10 wanted was revenge. Kakashi decided to follow them to add to their rate of success. But look at what became of Kakashi afterwards.
How is this relevant to the issue that Kakashi was complacent in their hunt for revenge when two hundred chapters ago he was lecturing to Sasuke that no good would ultimately cpome from seeking it out? Your statement here only substantiates the notion that there are varying levels of justification to one's pursuit of vengeance which characters can discriminately choose to support.
Seeing what Naruto did changed him. Naruto didn't kill Nagato and accomplished so much more, basically bringing Kakashi back to life but not only him.
Really? Was there a reference to this self-examination of his morality following Naruto's merciful reaction to Nagato? Did Kakashi recollect on his assisting Team 10's quest to hunt down the Akatsuki? Was there an acknowledgement that his actions there were wrong or that there can be be no absolute adherence to the ideals of mercy and condonation? Your retorts here are beginning to resemble what I fist stated about Team 10's actions being reclassified as something other than revenge. You can argue that they had not yet accepted Naruto's precepts as their own or that they were ignorant of the repercussions of their actions but please do not attempt to refer to it as anything other than revenge.
So he decided to trust Naruto regarding the fourth Raikage. Also when he confronted Sasuke he adressed the issue of revenge.
Yes, and he resolved himself to kill Sasuke, not because of some personal wrongdoing that made Kakashi begrudge him, but because he felt that it was the most logical approach to handling Sasuke after he refused to listen to reason. Kakashi's actions were motivated by practicality, not emotional embitterment.
Therefore if at the moment when team 10 wanted revenge he was ok with it, right now he is against it.
You do understand that he was arguing against people acting out of personal retribution before Naruto even had an understanding of the concept, right? In chapter 177 he explained that he understood how far people like Sasuke could sink in their ambition to exact their vengeance. Interestingly enough we see a mild example of this when Team 10 was disputing against Tsunade prohibiting them from continuing with their mission. Kakashi pointed out that they were going to carry out their mission whether the Hokage agreed or not. This blatant dismissal of orders isn't an example of someone who is taking an unorthodox approach to get what they want?
Oh, and it's ironic that you should bring up Kakashi. By his own admittance he stated that if his cherished companions were killed that he would likely do everything in his power to exact revenge. He declared that as he was attempting to convince Sasuke to give up his vengeful ambitions. So by his own word Kakashi is a hypocrite.
Not sure if this will be the case in the future. Right now we did see him have resolve to fight Obito ( probably to the death) but it's not about revenge. In fact he should be on the receiving end yet Obito doesn't blame him.
Because Kakashi understands that he too has made alot of mistakes in life as well. He even referred to himself as "garbage". How can you preach to someone you yourself are guilty of your own transgressions? I will admit that his words here display a greater level of maturity than anything before that point. He isn't denouncing Tobi's motivations like he was with Sasuke partially because he understands that the allegations made against him about being unable to protect his teammates is true which is one of Tobi's most significant driving factors behind fighting to bring about the Moon's Eye Plan.
And I think it will be adressed in the near future.
Will it? Or is this favouritism going to remain unaddressed?
As I said Shikamaru right now considers it a duty to kill Sasuke so that a war be avoided. Something that was born out of his act for revenge.
Yes, and I already addressed this several responces above. Shikamaru has no personal understanding of Sasuke's motivations nor did they really interact with each other. He treats it like a formality, not a personal vendetta similar to how he reacted to Asuma's death. Shikamaru's conveniences lie in that ignorance and the lack of personalized infliction of harm to those close to him like Sasuke harmed Raikage's people, specifically his brother.
His desire for revenge made him realize that the same can be done again. But if we look at the manga his way of thinking is wrong. And Naruto will have to change it.
Are you referring to Shikamaru or Sasuke? Because if it's the former then that situation has already been concluded. His psychological endurance was never challenged on any level like Naruto's was when confronting Nagato. He had already exacted his vengeance against Hidan. Coming to realise that your method of thinking is morally unjust loses its impact somewhat if you have already acted out those unethical impulses. Would Shikamaru continue to disregard Tsunade's orders if he understood what Naruto's words meant back then? Or would he persist in carrying out this futile attempt at "justice"?
