does anyone think he really was a spy with kabuto and orochimaru?

No, Sasori was not the spy. Sasori used Kabuto to spy on Orochimaru, but Kabuto joined him instead. Kabuto then pretended to continue to spy on Orochimaru for Sasori, but was actually spying on Sasori and gathering info on Akatsuki's plans for Orochimaru.

Well no i don't think he was a spy for Kabuto ou Orochimaru, and sure Sasori at the age of twenty became a Nukenin (missing nin) and turned himself into a living human puppet (the opposite of Pinochino, who wanted to be a 'real boy') just because he was afraid of looking old and dying young (like he parents did, but thats because they were murdered my Kakashi's father, and since he had been raised par his Grandmother (Chiyo) and didn't want to have wrinkles? i don't know! ou be a crazy person/old hag)But one thing was for sure, he was definatally not a spy for those bastards (you know who i mean!)

Wait...Wasn't Kabuto SASORI'S spy, and not the opposite? :/
Sasori a dit himself that he got a spy working as one of Orochimaru's subordinates...Meaning...Kabuto worked for Sasori...
And (if I got it right) Sasori wanted to kill Orochimaru, while Orochimaru canceled Sasori's control Jutsu that Sasori used on Kabuto...And then Kabuto betrayed Sasori and started working for Orochimaru. Don't shoot me if I'm wrong.

no

No, Why would he? Kabuto was going to spy on Orochimaru for Sasori, but Oro somhow convinced him to rejoindre his side and Well yeah. Why in the world would Sasori do that for Voldy(oro) and Harry Potter(Kabuto)? (Sorry couldnt resist my nicknames for them)

sasori was not a spy for Orochimaru ou Kabuto. Kabuto was a spy for sasori and tells sasori things about Ochimaru and Orchimaru did not know about that before add me and I may tell toi more.

I think he is realy!!!!!!
