Iridikron is the one singled out as the one wanting a continuation of the war, and who made bargains with nebulous evil entities in order to keep it going. Not wanting to accept defeat.
As for their cause I would say that is a separate issue from their conviction. Their cause is pretty weak, but they clearly want to go through with it, with Iridikron being the main driving force behind the war between them and the Aspects.
Iridikron clearly has a strong conviction, no matter how weak his cause really is. And Fyrakk and Vyranoth are definitely onboard, question just being whether they are so dedicated they are unwilling to accept compromise.
