What we learn from this is that people will resort to violence if they can get away with it when it provides them with benefits. Some may be predisposed to behaving in this way, others probably discover the effectiveness of such behaviour early in life and once they have done so continue to exploit it. We are all familiar with such individuals, the much-to-be-feared thugs and bullies. Though they rarely make good friends and we can never trust them, we often have to learn to live with them.
