As somebody who analyzes the psychology of criminals for a living (I’m a Risk Mangement and cyber security architect/executive), I can tell you that most of these people do not think they’re doing anything wrong. They have a real objective, as you describe, which is completely outrageous, but probably true. And they want this so badly that they will twist their perception of reality to convince themselves that there are other reasons why, for example this bill is bad. They are unaware of their own biased behavior, they are convinced they are right, and they will literally fight to the death. The only way to stop some of them is to throw them in jail, and even then they won’t think they did anything wrong.
