Conspiracy!
You know what?.... What Tobi/Madara is telling Sasuke is real.... dramatic and looks like it could fit into place... but this is what i think...
Madara lost to freken Senju First Hokage in taking over Konoha... He's obviously still butt hurt about it and wants to take Konoha down like eversince forever. What better way to win it all back by telling Sasuke this incredible LIE that Konoha's responsible for Sasuke's family's death. Of course Tobi's gonna tell Sasuke-sama that it's Konoha's fault,... with sasuke's grudge towards Konoha now,... what in hell could stop them now?.... No... No way Konoha's responsible for this... TObi's all TALK...... He can't use his Genjutsu on Sasuke so he'll play with words and brainwash the fool... by the way.. i've always wanted a private message... one would be great from anyone.. HOLLA.. ciao.
