The reaction here is as bad as a child who found out Santa isn't real, after years of defending their position that he is.
Except this is a little more whiny.
Kishimoto's target: children. He'd probably laugh if he found out how much of an older teenage/adult audience he has who take the plot this seriously.
The fact remains that it's not completely illogical for it to be Obito. To me, it has "Sosuke Aizen" written all over it. Someone pretending to be inept to avoid attention, who's from a clan known for young geniuses, and for not always seeing eye to eye with the rest of Konoha, doesn't seem that unlikely. I mean, Kabuto did the same thing.
It's much easier for me to believe he was a genius under someone's guidance than a dude with no eyes surviving 88 years and stumbling upon Obito's corpse in the woods under some rubble. lol
Many of the past events could've truly been Madara, and he probably found someone to train and work in his absence. Could also be how he was prepared to be resurrected someday and knew how to sever the contract for the Edo Tensei.
Look how much Sasuke learned in 3 years of training with Orochimaru. If Obito had a better sensei his whole life, it's not unlikely that he could've learned everything he did by 14. Susanoo could've released him from the boulder. Furthermore, the dimension to which Kamui sends things might not be the only link between him and Kakashi. Maybe Obito was ordered to give him the eye as a way to spy from afar.
Being close to Minato, he could've known the approximate time Kushina was due.
If Infinite Tsukuyomi was the goal, why would a master tactician with control of the Kyuubi waste time attacking Konoha when escape was guaranteed (Kamui)? Sounds more like something a kid would do in disobedience who's flexing everything he's repressed for so long.
Maybe Madara WAS responsible for the inception of Infinite Tsukuyomi, but Obito just became a torch runner in later years. Who knows? But there's no sense in getting mad if my prediction's wrong.
Nobody has a right to be mad at Kishimoto just cause being presumptuous made all your broody-goth, anti-conformist, convoluted arguments about a children's story WRONG! lmao
