The criminal does not know what moderation is! In his thinking and behavior, he more frequently than not goes to extremes. It is critical to understand this aspect of his psychological makeup. Failure to do so can endanger a person who interviews, attempts to counsel, or in other ways interacts with a criminal.
In his mind, the criminal must be number one or else he counts for nothing -- an intolerable situation. You can see this even when he is a child. If others don't play by his rules, he refuses to play at all. If he is not recognized as tops in any endeavor that matters to him -- e.g., sports, academics -- then it isn't worth doing. Even in a menial task in prison such as buffing a floor, it must shine. If someone steps on it before he has completed the job, he becomes furious. He is indiscriminant in this view that everything he does must be tops and recognized as such by others. Everything has the same importance. This is not a quest for excellence but a result of his own pretensions.
The criminal demands that others recognize him as "number one" when it comes to work. If he walks into a restaurant seeking a job, he believes that he should be the manager, not a "lackey" who has to undertake tasks that he regards as beneath him.
