That also means he wasn't doing it to save the world. Nothing about Orochimaru has changed, just his approach has. There's a difference.

Reason for saving the Gokage? The Gokage will owe him a favor in the future.

Reason for fighting against Madara? So he can continue with his inhuman experiments and get Sasuke's body.

Reason for summoning the four Hokage? To destroy Konoha after his one last attempt to manipulate Sasuke into staying on that path (given how he immediately zeroed in on Tobirama).
