This cultist, a high-ranking member often by the leader's side, suddenly realized something was off with his boss.
The guy was acting like a totally different person, hell-bent on a do-or-die clash with the authorities.
During his impassioned and misleading speeches, he talked about initiating the final judgment, summoning "Our Lord" to cleanse the world of filth and create a utopia.
As a senior cult member, he didn't buy into this nonsense.
He thought his leader had lost it.
Their so-called God of Truth was a myth, and even if such a deity existed, how could they, mere mortals, summon it?
He became convinced this leader was an imposter, maybe even swapped out after being offed by some mysterious figure!
The atmosphere in the cult grew increasingly terrifying.
Those fanatics were transformed into senseless, pain-immune monsters, blindly obeying the leader's commands.
