hierarchies are everywhere
Naturally there exists a spiritual one
higher vibrational beings w/ highly developed senses at the top
and lower vibrational beings with dulled senses at the bottom
I don't know what the soul is but I assume it can either grow or die-much like your physical body (we often hear of soul healing/sickness etc.)
I agree that NPC exists, however
it would be hard to find a person with absolutely no soul
what comes to mind are the ruling elites with their Satanic cult
If someone denounced ownership of their soul then he would free himself of karmic debt
and might enjoy many lifetime's of degeneracy and comfort under Archon's rule in exchange for ...?
now think of society and how many people can actually pull of something like it without getting divine retribution
If the average 'NPC' really had no soul then we'd see serial killers thieves prostitutes at every corner
In contrast average people who attempt this life lose their humanity and won't reincarnate in this form
that's how we have balance
