yeah sasuke had always been a selfish dude.. And as for obito and madara.. I think madara would kill obito just after he shows his real intention ( surpassing everyne including hashi and so6p)This is very true... the Uchiha are all very double sided. Itachi who let himself be seen as a villain turns out to be "good"! Sasuke manipulates and uses people to get what he wants. Obito let everyone believe he was dead then made everyone think he was Madara... They are all very self serving people. Let's see what Madara's true intentions are to prove the pattern Uchiha personalities tend to display!
Yup I have a feeling Obito will really do something to force Madara's hand against him... he'll probably end up dying in Kakashi's arms and have a last moment of remorse and sorrow!
Oh he did betray Orochimaru... he told Orochimaru and Naruto... "I don't care what Orochimaru does with me as long as it kills Itachi" when infact he had no intentions of letting Orochimaru control him!
Hey no worries... that's how conversations roll!
For the record... I agree! Sasuke has no loyalties other than to himself!
