What if... "Tobi" was an idea?
This video has a great theory of Tobi, and if he was an idea not a person.
Remember his statement:
"Those who break the rules are trash, but those who abandon their comrades are worse than trash!
If I'm going to be called trash either way, I'd rather break the rules!
And if that somehow makes me anything less than a real shinobi, then I'll crush all of the so-called "real" shinobi!"
Perhaps we all thought "Aw, how sweet", but this sounds like a very radical notion to me now. And look at the shit Konoha has pulled off in the past years, decades... They feed the young generations with illusions, wrapping it up nicely and sell it as their so-called "Will of Fire".
