An interesting tidbit about demon psychology: playing back a recording of things they have said or reading to them any document that describes any way they have broken the law invariably angers them to the point of action, which may include violence.
This information is useful to me in detecting demonic involvement in human criminal affairs; if I need to uncover human collaborators, I describe crimes other human collaborators have committed online or in court documents, and then watch who moves against me.
Having done this for nearly 6 years, I am intricately familiar with who—and how—demons are helped in perpetrating injustice.
Stories of how this has worked for me in the past are coming up.
