People rarely repent. They become "religious" in order to keep deceiving themselves; few get really sick of the lies. It's always about some outer being or whatever that could help them inside the illusion. Why would they ask for help to get out of it? They don't care if there's no real thing inside them when that's not necessary to get the life with all they've ever wanted. On the contrary, it'd ruin their plans.
Yes, the void is necessary to "success".
Consciously or not, they are aware of that.
