I found an article that describes the psychological process on display in the video:
https://www.psychologytoday.com/us/...-believers-the-psychology-conspiracy-theories
I'll summarize the key points of the article:
fundamental attribution error - the notion 'it's not random, somebody did this'
confirmation bias - look for the evidence that'll confirm what you believe, ignore or downplay other evidence
belief perseverance - actively dismiss evidence that will refute your belief
People feel less powerless if they're within the special group that's 'in the know'. 'Other people don't know what's really going on, but I know what's really going on'.
pareidolia - pattern-seeking behavior gone overboard. Like the way the guy thinks he sees a "falling building" on the folded bills. Just like a face in a cloud, there's nothing of the sort there.
From the article:
Our brain seeks order, cause and effect, and intentionality. But life is filled with chaos, blind chance, illusory correlations, and disorder. When these conditions impinge on us we become distressed, and to reduce the distress, we are compelled to make stories that fit the demands of our brain, rather than the facts of the world; stories in which intentionality, order, coherence, and purpose exist, albeit in hidden form—e.g.: conspiracy.
For persons who feel the government is malicious, knowing their ill-intent is like knowing what the predator that might eat you is up to. So, feeling that you know helps one feel less helpless and distressed.
Then the article gets around to comparing this to religion. Religion shares with conspiracy theories the traits described above. The "othering" in both is noted: "The same psychological processes that produce God for 'us,' produce conspiracy theories about 'them.'"

My commentary: You see the "us" versus "them" paranoia in his talk about converting people. He says he has succeeded at scaring people, to make them vulnerable to evangelical bullshit. His message is in effect: "The enemy is out to get you, the whole world is filled with deceptions and malice. So you better get God on your side!"
It's weird to me, because his plea ("This is a wake up call! Time to wake up!") simply has no appeal whatsoever. If he were able to figure out a way to make me feel scared, my response would never be "I need to get religious".
