Hey, thanks for the comment.
I agree with a lot of what you're saying, but there are key differences between our ideas of how things are going to turn out. If I am understanding you correctly, you are saying that because of what the Juubi is doing, or did, or is going to do, it is evil. Maybe not "evil", but it understands what it is doing and actually harbors feelings against people and to this point I disagree. You are comparing it to shinobi like Obito and Madara who believe what they are doing is "right", but because of the way they are going about it, they are inherently wrong ( with the killing and things like that). But, the Juubi isn't like that. It doesn't have a sense of "wrong" or even "right" for that matter. The best way to explain it, "It just does what it does...". You have to seperate it from any ideology because it has none. It isn't doing the "right" thing the "wrong" way, it is not just another antagonist. It is supremely a force of nature, that acts only to preserve itself.
And I have to disagree with your point about Naruto. "I am Naruto, the strongest shinobi to live." Is an idea that got the world in the mess we see it in. He has to seperate himself from that thinking. He is going to realize the truth about the Juubi soon, and because of this fact he won't become it's jinchuuriki. And if he does, it will be briefly before it is allowed to return to its rightful place. The series has to end with the Juubi returned to the world, the Sage fortold it. It is the only way to bring balance.
