Benton County Trilogy

There is a growing body of research today documenting the psychological factors of fear and hate and the link to those who believe in unfounded conspiracy theories. It has been reported that the victims are often; suspicious, untrusting, eccentric and fearful as they are living in an increasingly dangerous world. They see patterns where there are none. I have tried to understand how they can believe in such outlandish conspiracy theories, for example, that Climate Change is a Hoax.
In my simplistic world, other than dementia, there are only three impediments to clear thinking, they must be either; Stupid, Ignorant or Crazy.
For my story, I wondered, what if someone was afflicted with all three. How might a character behave if he were both stupid and ignorant and also crazy? There is a wonderful quote in Nikos Kazantzakis's, 1946 novel Zorba the Greek where the character Basil ask Zorba if he ever married. Zorba answers, "wife, children, house, the full catastrophe."
I would like to borrow the quote to describe the villain in this story who is; stupid, ignorant and crazy and also mean as hell. The Full Catastrophe!
