Honestly, it would be interesting if they're a system that connects to another system. For instance, since in Mythology he is the one that sends or delivers the souls to underworld then their should be Charon System or Judges system which could make an interesting dynamic. No one is truly good and sure I don't think being abused I have had my fair share but I my Mother taught me in giving second chances of they fail constantly. It's not our own to judge them but God's. Just my fair share
