Sociopathic
This person is a predator. They feed off of any type of harm they can dish out on others. They do not see things the same way that most of society would see it. Crime is nothing but another way of life for them and most of them are knee deep in crime by the time they are fourteen.
This Persona has no conscious and rarely even can control their violence once someone finds the right buttons to push. (Most people will blow up when the right buttons are pushed, but the Sociopath will explode and deal great deals of violence on others, up to and including murder.) They have no remorse, no empathy and view things through such a skewed lenses that if they were to tell people what they were really thinking, they would probably jailed.
Due to their nature, the Sociopath does his/her best to learn everything about the human condition so that they can “fit in” to the “normas” of their society. They usually will stick out like a sore thumb amongst their peers. Often they are the head of something, running for something, leading something, this sort of thing. They believe that through leading and volunteering to do things, they can hide their true natures and for the most part they can.
This Persona will often run into conflict when things become highly emotional. They simply do not understand emotion and will mimic what they have seen and some of them are incredibly good at it.
This is where most of the actors, some lawyers, a great deal of politicians, and higher office holders. This person will always seek out power and try to find ways of obtaining it.
Crime is nothing to them and the idea of reporting a crime that does not benefit their goals is laughable to any of these people.
