Headscratchers / Banishers: Ghosts of New Eden

• How are banishers able to "kill" ghosts with conventional weapons?
  • The attacks deplete their essence. The game only mentions it in passing, but as they lose essence, ghosts become specters, and specters become wisps, each more fragile than the last. The attacks speed up the process.
• Why doesn't Red destroy corpses when he sees them? They're just going to become bonewalkers and the settlers certainly seem to just not care what happens otherwise.
• How do the various religions of the world square their theologies with the basic facts of banishers running around sending people to the afterlife, especially as the game confirms banishers can arbitrarily send people to Hell at their sole discretion?
  • That is an incredibly fascinating and disconcerting point, makes for interesting world building, though. Perhaps they are considered mortal agents given abilities from a higher power?
