Hmmm, why would OS consider going against Tartarus is in their best interest? They only know that they're Demons from Zeref's books who are finally making their move. OS isn't suddenly good and going after the bad guilds, neither do they know anything about Tartarus' plans. Not to mention that they'll hardly trust Jellal and, by association, Meredy. Same applies for Zeref, who they still consider dead. Why would they suddenly believe Jellal? Well, Mashima could make it so, they're not real-life chars after all, just saying that these are, imo, reasons why they wouldn't help Jellal. So the point of them working with Jellal would never arise. But, again, end decision is with Mashima, he could just skip these arguements.

I ... don't even know whether OS know that Ultear was controlling Jellal or not. For all we know, they might know, and might not even blame him at all; I'll even say might pity him a bit, like Azuma (or is that anime-only? meh, who cares). But that doesn't mean they'll suddenly join him. They have no reason to. They have no reason to trust Jellal; after all, he is making the same promise that Brain made. Neither do they have a reason (that they know of) to fight against Tartarus or to believe that Zeref, the guy the ToH was built to resurrect, so the root cause of their misery, is alive. But they have every reason to fight against him, to seek their own version of freedom. Not to mention the personality clash I pointed out earlier, even if you remove the childhood hatred part.

In the end, though, I think none of this will be taken into account and they'll just obediently follow him. :c ... And I take back my statement of Jellal dying in this arc; there might not be enough time. >.>
