There are four kinds of people in the world. Actually, there are many kinds of people in the world, but we will just focus on four social types in this proposition:
On the scale that measures individual conformity and adherence to social, moral, cultural, and legal conventions, there are:
1] Those who reject all authority (social, moral, cultural, and legal) and will never conform to any applied conventions whatsoever. We tend to label these personality types psychopaths and sociopaths. The "wolf-major."
2] Those who are likely to reject authority, but will skate the boundaries of "compliance" so as to mask their true nature and intent when necessary. We tend to label these people anti-social personalities or criminals. The "wolf-minor" or wolves in sheep's clothing.
3] Those who are chiefly compliant to all conventions but only because they fear punishment or reprisal for breaking the rules. These will from time to time find themselves shifting into the spectrum of  under certain circumstances, but rarely by intentional choice like . The "sheep-minor."
4] Those who fully embrace all social, moral, cultural, and legal conventions and are unlikely to never knowingly commit a crime or transgression on purpose. They go out of their way to obey the rules. The "sheep-major."
Now, on the surface, it would seem that the ones we should fear most--the ones who could potentially cause the most trouble--are  the wolf-major. However, wolf-majors, the psychopaths and sociopaths account for less than 1% of the population. In addition to this, the number psychopaths and sociopaths that are outwardly violent or disruptive to society is even less than that 1%. And further, despite their blatant disregard for all things authoritative, psychopaths and sociopaths excel in their ability to hide in plain sight, a skill they perfect during the lifetimes. So people are often completely obviously to their presence, making it difficult to attribute any real malfeasance to wolf-major.
The one which causes the most trouble, violence, and disruption in society is  the wolf-minor or criminal. They number anywhere between 4% and 10% of the population (depending on who you ask)--a number that can significantly affect all aspects of our civilization. Difficult to predict since they often manifest as just "normal" people, we often find their behavior simply being tolerated in much of society, either out of penal laziness or having no solution available (copyright infringement), the cost of prosecuting minor crimes weighted against the benefit (jay walking), a lack of ability for dealing with the problem (rape, murder, theft, and fraud), or being unable to reproach the criminal because they have managed to achieve a position of power and influence which protects them from prosecution (government corruption, war crimes, corporate greed, the rich who can afford teams of expensive lawyers).
As for the percentages of  the sheep-minor and  the sheep-major, those have thus far proved difficult to calculate by researchers. However, my prediction is that the largest majority of these four categories would be the sheep-minor--probably more than the other three categories combined.
