Shouldn't be hard to understand. The fallen trash can only harvest their own souls that they send here to play the game on their behalf. So there is a "deal" for them to be able to hijack them after death. When those traitor collaborators die...remember that they were part of the negative invader force EVEN BEFORE they were born. Not all humans are human spirits and the spirits here are leaving so the game can collapse and be cleansed of this corruption. The energy will be recycled and these beings will cease to exist. Souls are just another vehicle for a consciousness...no different than your meatsuits here on EArth.

There's a tid-bit here about spirits and humans that I may as well add:
All humans have existed as spirits and may have likely been humans before (re-incarnation)
but not all spirits have necessarily incarnated nor experienced being humans/homo-sapiens.
And in Legalese the word «HUMAN» actually had the historic-definition of being a Monster.
