This^^^. With his upbringing, it would have made sense for him to flip the switch instead of Sasuke. Four tails Naruto would be unstopable for most shinobi
I see no scenario in which Obito survives this war other that being revived after his death. All is forgiven with Sasuke...just don't expect him to become Hokage. Oro for the final villian
Not with the time frame that he has planned out. Besides, people complain that he is dragging out the story...writing about all those characters will only make it worse
