Or, you know, the Arbiter lied to all the Elites.
Think about this: How did the Arbiter get all the Elites, Grunts, and Hunters to join him with the snap of a finger? Surely he didnt tell them that everything they had ever believed about the Great Journey since they were children(or whatever they are) was wrong. The Arbiter himself didnt believe it until 343GS told him.
The only logical answer to this is that he lied to them. He told them something like 'The Prophets arent bringing us along on the Great Journey.'
Naturally, once the Elites found out he lied, they would rejoin Truth, and end up fighting humanity again.
