Some say Obito being Tobi is what ruined/killed Naruto.
How did you feel about that revelation? Why?
That wasn't really the case for me.
I think what was taken away from the revelation was the chapter name. the way it was executed was decent, it could've been better, but overall I thought it was decent.
granted when it came to his attention it kind rubbed me the wrong way, but by the time his fight with Kakashi came in the other dimension I did start to like him from there. It didn't kick off until he started to regret that he became a personal favorite of mine. Now the main issue when it came to people's hate on Obito was "You Let Rin Die!" they were like oh really all because of a girl, yes but in the end she (at least to me) dis reciprocate her feelings and by telling him she's always been watching him and waiting for him." The other thing is Obito was 13 when he lost Rin and there's always a saying Love comes with both light and darkness. Another case you can look at it is when Anakin fell to the Dark Side in Revenge of The Sith ultimately he did it because of Padme. That's something you can correlate with Obito too because he was doing all of it for Rin, I wouldn't really Obito a villain, he's what I considered The tragic anti-hero ultimately doing what he believed what he was doing was right for the world. It's not until after he saves Naruto's life were I consider him as a tragic-hero.
Point is people find it idiotic that You're doing all of these horrible things because the love of your life died. That's something most people don't really notice because if you've got someone that's precious to you (platonic or romantically speaking) then of course it's going to be hard for you. Plus consider the situation Obito was in, he was desperate to save Kakashi and Rin and to see his friend stab Rin right before his eyes was something he didn't want to see. So of course seeing that for him meant everything has now become hell.
That is how I see it when it comes to Obito's character, he didn't kill the series at all because it didn't degrade Team 7, or Madara, or anyone. Well O okay "The coolest guy ever" comment slightly I wouldn't say that killed Naruto's character. We've got The Last to freely say Naruto has now decscended into Scumruto.
