guys let me just repost what I said from a couple weeks or days ago...
"I think the reason
Tobi became how and what he is right now has something to do about a character that has been overlooked and neglected by many but holds great importance to Obito and Kakasahi.
That's right I'm talking about Rin. As we all know she died but unfortunately the reason and events behind her death are still in the Kishi's locker, it's still unknown, a mystery.
I believe Kishi meant it this way because the
story of her death holds the
explanation why Tobi turned into a madman. First we all know that Obito loves Rin now let me direct you to that eventful day when Obito was stucked under boulders of rocks, He decided to give kakashi his right eye as a gift then he made a request a 'WISH' for Kakashi to take care of Rin. Kakashi took it by the heart and decided that he would be Rin's protector even stating that he(kakashi) would sacrifice his own life just to save Rin if ever it needs to come to that. BUT we all know that Kakashi failed 'cause Rin died for some unknown reason.
Now, another thing that struck me was Tobi's line in the latest chapter(597) wherein he said to Kakashi: "You've seen reality, you should be able to understand...No 'WISH' can become true in this world" He really sounded like a really bitter person to me, like he is carrying something heavy inside.
I think those lines about a
WISH implies something deeper. Maybe
Obito during his recovering and brain conditioning years with Madara covertly witnessed Rin's death and Kakashi's short coming of protecting her. This convinced him to totally go with Madara's planas the only solution for the shortcomings of the shinobi world. Furthermore Tobi also said in chapter 597 that he 'wants to make a world where HEROES don't have to make pitiful excuses in front of graves' now we all know that this is a pun to the failure of Kakashi 'the Hero of the Sharingan' to fulfill a dying Obito's sole WISH>>>There was a flashback scene showing Kakashi standing before a grave.
As we all know, my thoughts are interpreted from translated materials so I'm really not sure if the wordings were correct from the original Japanese meanings, but hey based on what i read these are my thoughts.
Anyway, thank you for reading. What's your take?"
I would just like to add that I think
Zetsu, Orochimaru, Danzo and Madara had samething to do with Tobi/Obito but as of now it isn't that clear yet
*please to all those people who are saying Kishi is trolling or that he just pulls stuff from his behind, just quit it, hahaha coz you're making a fool out of yourself, a writer can make his story the way he wants it to be. Kishi is professional writer he knows what he's doing everything has been planned all along but unfortunately some of us just won't take it...just chill and enjoy the story everything has an explanation...

xD
and oh yeah before I forget.....
WE TOLD 'YA SO!!!!!!!!!xD
