Literally every Uchiha in the cast has either hated Konoha or at least pretended to in Itachi's case. Maybe he did some reading and decided they sucked? I don't know. As for Obito being dead, that's a problem with any guess at Tobi's identity. Izuna is dead too, and according to the wiki we even see his dead, eyeless body going into the casket in a flashback. Keep in mind that during this arc virtually every named dead individual was returned to life, so someone coming back from the dead in the past isn't exactly a stretch. As for the power up, why do you say he needs one? Keep in mind that nothing Tobi has done actually requires a lot of chakra. Assuming his body is an Uchiha, he can use the spacetime jutsu from Obito's eye much easier than Kakashi can. He mindcontrolled the 9 tails, he didn't overpower it, and in fights he never does shit directly, he just phases out a bunch.
