The multiple demons thing is an interesting theory. I think many of them have specific purposes and motivations at odds with each other, in at least a competing-for-victims sense and perhaps others.

You have to wonder though, thinking about how frequent rants about covid and vaccines are VS the frequency of the vax-induced type failing that this woman went through.. what are the chances these happen to overlap? Its kind of like a Q zero-delta thing.. except this time its God saying 'oh no you dont'
