It's hard to understand if you don't feel like I and many other do. It was the build up to.. how Tobi was represented, how big his influences were on the shinobi world and of course: the last part of Naruto Manga. This story ends after this war, this event is the " climax " of the story. His reasoning is something what could/should have happened way back in the beginning, a side-villain.. it would be perfect then, but right NOW: it's a shame.
- You can't say it wasn't only " RIN ", he himself clarifies it and of course; by reading this chapter, it was all clear why that whole chapter of flashbacks from LAST WEEK. Rin was in the spotlights last week, and right now:
Obito: " I leave Rin,.. to you "
Obito: " wether *I* survived is not important. However, Yeah.. IF YOU REALLY WANT TO KNOW WHY,.. IT'S BECAUSE YOU LET RIN DIE! "
That page above, says it all. " The darkness " inside of him that you speak off, was his " loss " of RIN and his " faith " in Kakashi.. Madara has played that part and took it captive for winning his trust. Even thinking about it: maybe Madara didn't even did try that hard for convincing him.. like you said: Obito had hope for so many things, but didn't achieve anything. This could be his major jump to the darkness of HOLLOW, but in my EYES: it's very weak to make HIM " the biggest " mysterie of Naruto Manga.
- I even found it very lame that Madara Uchiha chose him for taking on his Master Plan.. someone of his calibur putting everything in the hands ( like you said ) weak person who cried all the time, had big hopes but didn't achieve anything. " POWER " is everything for Madara Uchiha, so even that part of him entrusting his ressurection in Obito's hands is for me, very poor writing.
And you're speaking of him facing lots of " failures " like he has lived and breath 30 years like Kakashi.. he was 11-13 years old, he had yet to begin facing the true world, true loss and all the responsiblity that comes along with it. The " PAIN AND LOSS " that Naruto, Sasuke, Gaara, Nagato and even ZABUZA in a far more younger age,had faced more painfull and cruelevents then Obito.
So, basically,.. if RIN didn't DIE, he wouldn't do all of these stuff. It was from the beginning Madara's Master Plan that he carried out, but the person who carried it out " Tobi ", the msyterie that was build around him needed to have a WOW factor. A revelation that should've suprised us all, a epic plot twist that should make us all like; Unbelieveable, that Madara is a sickfuck etc.
IF TOBI was his;
1. Izanagi creation ( with Madara's knownledge), with partly Zetzu ( EPIC! " No- One "; that cruel, heartless actions would be more fitting )
2. Izuna in Obito's body, partly Zetzu ( EPIC! )
.. OR even something entirely different, but better then just Obito=Obito. I mean: you could every little detail, but is how the world is.. and Naruto is going to stop that circle. If it wasn't for Kakashi, he would have died immediately by that attack that destroyed Kakashi's eye. If it wasn't for Kakashi, he coudn't even died by giving a present to Kakashi and holding Rin's hand for the last few seconds with her shedding tears for him. On top of that; EVEN IF HE COULD CONFESS his love to her, she wouldn't except it.. just like Sakura.
Rin LOVED KAKASHI, you know that, right?? It was shown in Kakashi Gaiden.. so what would've happened then; when he would hear from her that she didn't love him at all?? He would be all like; ooohh oke, fck the world, I BLAME THE WORLD for why she doesnt love me!
This all tiny details is what I mean with; " not fitting " as a Akatsuki leader, BADASS ViLLAIN who made Minato sacrifice his and wife's soul, by putting half kyuubi inside of Naruto.. A NEEDED POWER FOR KILLING " TOBI ". Tobi, with his reasons and history,.. wanting Sasuke that badly and made Itachi prepare all those stuff for keeping sasuke away from him.. the WHOLE PICTURE is just simple LAME.
** By reading the last part that you've edited,.. it's pointless for explaining my thoughts, and sorry; I need to " COOL IT? " If I don't like it, then I don't like it.. that's what this forum is all about. You're talking about a TINY THING, it's not a tiny thing for me, it's a MAJOR THING.. that's probably what you're missing. This is NEAR THE END of the manga, it should be more then this after waiting 5 years for him to reveal his true identity. Don't like my post, don't fuckin react to it bro,.. that simple.
You want me to accept that Tobi = Obito? How can I not accept that.. it's a fact. But the way it was build up, was less intresting then I thought that It would be.
