re: Is there a “invisible hand” or “spirit of evil” that’s responsible for the current turmoil

I believe there are those that have turned over. If you reject God long enough perhaps he will abandon you.

Then there are those who could never have the light in them. Satan's sons and daughters from birth. They know what they are, they know they are never going to heaven, they are unsaveable. These are the pushers, soul stealers, world leaders. It is their job to extinguish the light in those born with it, work tirelessly to make Christ's children reject him.
