I didn't say that, Jellal said he would free them and that they would never be free when they are possessed by darkness, I just merely gave the opinion that Jellal will state that Zero is OS's darkness and if defeating him will free them then so be it.

Why not for Sema, with the state he's in and with no one to heal him, that the most-likely thing.
