Yes he should have been the final villain. He was supposed to be Naruto's final lesson that not everybody can be saved from their hatred and the guy needed to be killed for the greater good. The guy had too many chances because of the writer being bias to his Uchiha fetish. That clan and Sasuke get too much credit and screen time because at the end of the day, the story revolved around an Uchiha no matter who it was.
This bold! I got this feeling that someone just can't or IMMUNE to death in Naruto when i saw that everyone got resurrected at the end of Pein invasion arc. The war in Naruto is so pretty , it's not enough to make the audience think twice before wage war , i mean war is bloody and is scary , when someone make war in the fiction story they should depict the true horror of war so it can make people afraid and that it will not happen in the real world , but in Naruto the war is a joke , one of the main Character needs to die either Kakashi or Sasuke , sadly they resurrected Kakashi because hes too popular and therefore hes immune to death , as for Sasuke hes the perfect candidate but well ...... he got like 10 layers of immunity.
I don't mind Sasuke living, but he should at least be crippled, chakra coils damaged beyond repair, and/or end up losing his eyes. To ones like him and Madara, their eyes are more important than pretty much anything and are THE things Sasuke would have to lose if there's ANY chance of him possibly learning even the slightest bit of humility and such.
Agreed Sasuke is power hungry beast , if he going to get redemption then one of the best option would be strip him out of power and make him a normal human. Hes always in the sky looking down on people , he said it so many times to Karin and Sakura that shes useless. Give him that karma , give him some taste of his own medicine and make him lick his own spit and make him useless.
