Let's agree to disagree then
Expecially with the examples you bought, Fairy Tail is
all about friendship overcoming hatred, every fight is resolved by Natsu having a frienship power-up and then beating the bad guy.
Same with One Piece, and hell in Bleach you have Ichigo trying to understand and convey his feeling to the baddie everytime he fights an important battle, remember his comment about Gin's feelings being empty?
Or Ginjou being all "that bastard is trying to understand me and what I did despite us fighting and trying to kill each other" ?
In Naruto you have the fight you want right now, Madara and Obito vs Naruto and the Alliance.
Naruto isn't fighting to prove his ideology right, is fighting to protect the world and his friends. Shikaku himself said to Naruto that Obito ( and by proxy Madara ) weren't ones he could reason with, and Naruto agreed.
I don't see him putting out a book or trying to convert his enemies
So Naruto will not try to stop Sasuke? You either misunderstood what I said, or totally misunderstood what the Naruto vs Sasuke fight is all about.
I didn't say that, I said it makes sense if you look at it not with "Real life googles" on but "Manga googles" on.
Just to make an example, would someone irl save a friend he had for, what, 1 month, from the mondial government with a group of 7 people? And yet I don't see people raging about Luffy & co saving Robin.
Please answer me this, since you haven't replied finally to this question:
in Naruto's shoes, with Naruto's personality, what would you try to do to redeem Sasuke, knowing the guy can't be redeemed through words?
Give up on him is not an option, killing him in cold blood isn't either.
You are imo wrong on a fair bit of things:
-You would be right if, and only if, Sasuke wasn't Naruto's bff. If Sasuke was a random guy like, say, Kakuzu, then I would agree with you.
But we saw that Naruto is willing to fight those who harm him, no philosophical questions done
-You are generalizing wayyyy too much by saying "Madara had sharingan and kyuubi so he's right by that logic lulz", considering also that Hashirama kicked his butt despite all those things

-Naruto and Sasuke aren't all about Sharingan and Kyuubi, and even with those they have their own unique powers, as such that sillogism is wrong

-You see Naruto vs Sasuke as the pivotal fight of the Narutoverse, which is not:
Naruto isn't fighting to save the world, he's fighting to save his friend.
His fight to save the world is now with Madara and Obito.
But I see that we can't agree, so let's stop here
Of course is powered by human's chakra, even Kishi wouldn't give the Sharingan the ability to summon flames from hell

And if so, it would be hilarious than flames from hell wouldn't burn Karin or a Samurai's armour
Acid and fire works in a similar way, that's why I presented it as an example.
