This Sasuke "pawning" Orochimaru has to stop.
Orochimaru won this fight, and that is now indisputable.
To start with the mental part, Orochimaru had Sasuke believe he was I`ll and getting weaker even though hes body was physically weak and unable to even move but Orochimaru is never off gourd. As noted by Sasuke himself " lost his ambition and forgot his goal"..Now for me it was the strangest thing, Orochimaru didn`t say much, his reaction was almost unrecognizable. As he was absorbing Sasuke`s preach about the Uchiha. Now obviously the Orochimaru we all know Orochimaru is on of the most arrogant and self concentrated character. And there is no way he would lose his ambition and forget about his original goal.
Orochimaru completed the Transfer Process. He could of sliced off Sasuke`s head when he paralyzed him with the venomous gas, he had Sasuke paralyzed and at that moment, there was not any sign of anything that could hinder Sasuke from dying in that moment only Orochimaru himself.
He dominated Sasuke on the physical plane with white snake form, and had he wanted Sasuke dead, he would have killed him. Then, for all Sasuke's bragging about having "taken him over" in the mental fight, Orochimaru survived, and had his host all ready and prepared for him. And as he had all planned on meeting Itachi, he in my opinion underestimated Itachi, he believed Itachi would be the same kid who put pressure on him when they met, after planning ways to deal with Susano, (8 headed snake) Itachi's defeat of him via Totsuka (and let's face it, being defeated by something like Totsuka doesn't show weakness, it's just an extra layer of h4x that could have defeated anyone from the Narutoverse) Itachi saved Sasuke, but Sasuke had lost completely to Orochimaru.
If you fail to realize this simple logic then so be it^^
But next time you may state something like "Sasuke defeated Orochimaru" Then please, do come with a simple explanation that proves why your statement is correct.
