I mean people that manipulated him?
I swear he's the most gullible person in narutoverse that's why he always get controlled by the next guy stronger than him.
Well, when people say that Sasuke's been manipulated they're implying that someone's controlling his actions without his consent.
That's never happened in the manga. Ever.
Each time that a character has steered Sasuke into a position that they can benefit from, it's been by dangling a carrot in front of him (so bringing up the fact that they're stronger than him doesn't really matter, since they're neither imposing their will on him, nor overpowering him. They're buttering him up).
Orochimaru promised him the strength to kill Itachi if he comes to him. So, Sasuke came. That's not manipulation, that's bargaining. And then, Sasuke threw him aside and went on his way.
Itachi has been mindraping him sense early childhood; taking advantage of his hunger for vengeance. That's manipulation true and true, but the fact that he's been literally screwing with his mindstate since he was a kid makes it find. There isn't a single ninja in this manga that would've faired better if Itachi had done the same to them, lol.
Obito wanted Sasuke to stay around as a subordinate to either cultivate his eyes to steal later, or to use him as the sacrifice for Rinne Tensei so that Obito himself wouldn't have to die... so he promised him a bijuu to aid in his destruction of Konoha (goes back to the same situation with Orochimaru).
In other words, Sasuke's allegiances lie with whomever he believes he can benefit from the most. And it's not like he's gotten screwed over yet.
