Sasuke Has Not Changed
It's plain as day to see that this kid really ****in' hates Naruto. I have said this before and will say it again... Sasuke is not an avenger. He is a backstabber. He is always biting the hand that feeds him and the hands of people that reach out to him.
-He betrayed the entire village to go get more power with Orochimaru's help.
-He tried to kill Naruto to gain the Mangekyo Sharingan.
-He tried to kill Team 7 again in the beginning of Part 2.
-He betrayed Orochimaru, not because Orochimaru wanted his body, but because he found Orochimaru to be no longer useful.
-He killed Itachi and later regretted it, joining up with Obito.
-He later betrayed Obito and decided to do his own thing.
-He left his team for dead and tried to kill Karin after his battle with Danzo.
-He tried to kill Sakura and Kakashi.
-He declares that after all his backstabbing, he wants to be Hokage... but he still wants to kill Naruto.
Perhaps his motives have changed, but this guy sure hasn't. How can he expect to be Hokage if he tries to kill his fellow Leaf Village ninja? The village votes on who becomes Hokage. With his track record, he isn't getting the title, especially with his revenge factor.
