Destruction of Konoha
Member
Ok so there is considerable amount of debate on wether or not Tobi was "scared" of Itachi, thus holding his plan to attack Konoha, or that it was part of their "pact". Here's what I make out of this whole situation. Itachi was only alive before Tobi had obtained the rinnengan, so he was a bit less powerful as he is now. This being said I think that Itachi>or=Tobi (without rinnengan). While Itachi<or=Tobi (with rinnengan). I don't necessarily think that Tobi was "scared" of him, but more or less he had some sort of respect for him or the power he held and was unsure if he would be able to best him in battle (at the time). So, he just let Itachi alone knowing of Itachi's intent to die by Sasuke's hands. He just thought it would be in his best interest not to risk it.
That's just my two cents.
