So what. He was played as a hell of a villain that needs to be taken down since he was the guy that made world black and white. And then once he's revealed, he became like a whole new character that now makes us feel sorry. It can't work that way on a very short notice. Tell me, how much night and day were Tobi and Obito. You know how much difference they were. It has that awkward writing of one character not being revealed and being hidden, but once it's revealed to the audience, not the characters within the story, that character all the sudden shows you all the obvious note.@touken
That's orochimaru and madara.
Obito is not one of them. Obito is like nagato, in the sense that both of them will get change side.
He's not final villain.
I wasn't trained to get Tobi to be sympathetic or anything because it never got that approach. At least Pain was built that he had grey morales. As for Tobi, from him being presented as the mastermind to Naruto saying "You're much worse than Nagato" how am I suppose to believe he's made to be sympathetic. That's why people got so pissed on how he was written once the mask is out.
You're not wrong on his character status, but it's not wrong to think how it got into a big mess.
