I wouldn't say that, I would say that killing Obito like that would put a giant target on his back considering Obito was the real leader of the Akatsuki. All Orochimaru did was attempt to take Itachi's body and you saw how the Akatsuki treated him, they damn near hated him for that. So if Itachi did kill Obito he would have made enemies he didn't need to make, therefor interfering with his Sasuke goals.
