Oh Goddess After his alpha friend turns alpha fiend and psycho-tortures him into the abyss, a wannabe hero’s new revelation and divine intervention rekindle his forgotten mission to replace religion.

Hi Jay,

My brain just exploded. But I'm not sure that was your intention.

The wordplay ('alpha friend turns alpha fiend') is cute but replaces real specificity — 'wannabe hero' and 'alpha fiend' are generic labels, not concrete character details. 'Replace religion' is too abstract to picture as an endpoint or as an active, sustained pursuit; it reads as a stated ambition, not a visible goal. The causal chain from torture to 'revelation and divine intervention' to that mission is unclear and disconnected, and the sentence structure buries the action in vague abstraction rather than concrete beats.
The following looks more like a logline, but because I don't have specific details of your story, I'm sure it's not the story you had in mind:

After his best friend, now a cult leader, tortures him into a near-death vision, a disillusioned preacher's son sets out to expose the cult and build a congregation of his own before it consumes the town.
