It would be really interesting either through interaction with players or because players manage to join the Church of Light and work their way up the organization. If we as readers get to see the Church of Light become as corrupt and hypocritical as most popular churches in real life are. I am sure if priests or those related to a church in real life were to join the game where there is actual 100% proof of gods they would definitely join the only Church option they have which is the Church of Light. I just think it would be an interesting way to see players corrupting the NPC's and how the MC reacts to that.
