*heavy spoilers* The in-game comic shows that the Preacher was trying to save humanity from radiation poisoning through cybernetic implants. Some people feared this and ended up killing a lot of the people (now cyborgs) that the Preacher was trying to help. He went insane and created the Church to gather the resources to wipe out humanity. To soothe your butthurt even more, there's another preacher (27:23) that acts as a foil to the antagonist. You can go back to your epic sekrit basket weaving imageboard now, election tourist.
