I was referring to the other Titan Keepers like Hodir, Freya, Mimiron, Thorim, and any others who are still around. I'm well-aware of how much of a dirt bag Odyn is.. I'm just wondering that if he's the Prime Designate that he can directly control the other keepers and have authority over them.
Which is why if he does turn into the final boss for DF or becomes a potential boss, the biggest possibility I can imagine is that he's doing exactly as he was designed and created to do by the Titan's instructions as part of the Ordering of Azeroth... but he was too effective, similar to a machine or a HAL 9000 scenario where he puts his prime directive above everything else.
I'm fine with the idea of us having to kill Odyn, but I'm less fine with the idea of having to kill the other keepers, especially Tyr whom we've spent this whole expansion trying to reconstruct.
Edit: Come to think of it... if we end up fully finishing Tyr's construction and he invokes his authority on Alexstraza, only to get destroyed and prove right that we can't trust the Titan Keepers... then we'd just be repeating the same plot beats with Xe'ra in Legion when she tried to enforce her prophecy on Illidan, which he not only refused but destroyed her.
