My thought On Orochimaru and Akatsuki

[Darklor]

First Orochimaru came to Akatsuki as a spy but he suddenly left akatsuki everyone say that it was itachi who he was scared of
But i think the reason he came to akatsuki and taking itachi body was Orochimau had Madara's Body and he might known as well that Tobi was acting though as madara So orochimaru wished to prove he was not madara so in order to defeat tobi he knew that tobi was a sharingan user so planned that he needed a sharingan to defeat another sharingan user that is tobi Not able to successfully take itachi's body and make use of sharingan Orochimaru Left akatsuki and targeted Uchiha Sasuke. Therefore Orochimaru's Whole Revolution is TOBI.
how's my thought?

Good, but too convoluted. :|

Nah, too specific.

 

[Sir Blades]

I really dont see it as the cause for orochimaru really leaving the akatsuki.

Plausible but I doubt it. Good hypothesis though.
