It would be messed up if they actually brought about the end of civilization and this was all a test by a remaining sister civilization with advanced technological authority.

Those souls formed an afterlife coalition. The misrepresentation of those souls is the invention of the story of the ‘matrix’. They don’t want anyone interacting with the truth and so everything is ‘evil’. In reality, they created cybernetic ‘psychic assault’ organisms and these are wreaking havoc with human DNA which may potentially go ‘unstable’ and then everything evaporates instantly (months to years), not like a slow brain degeneration.
