Unrighteous dominion spreads like a fungus because it is not rooted in Christ’s fundamental teachings of love, charity and free agency. It demands, coerces, forces and leverages fear to spread its prideful, un-rooted and banal influence.
Applied and actionable free agency or thoughtful personal inspiration in the moment can empower each of us to liberate ourselves and each other from the chains of this this mental and spiritual prison. This is why the war in heaven was the only appropriate response to him that desired to imprison all mankind in a virtual prison of fear.
Arendt emphasizes that evil could spread “like a fungus on the surface” mainly because there is no depth, and that solely stopping ,and starting to think, can reach the depth. Arendt emphasizes: “It is indeed my opinion now that evil is never ‘radical’, that it is only extreme, and that it possesses neither depth nor any demonic dimension. It can overgrow and lay waste the whole world precisely because it spreads like a fungus on the surface. It is ‘thought-defying’, as I said, because thought tries to reach some depth, to go to roots, and the moment it concerns itself with evil, it is frustrated because there is nothing. That is its ‘banality’. Only the good has depth and can be radical.” (26) (emphasis added)
