It is not the social order itself that is the root cause of it all, but the attitude conveyed to the young people that they as an individual do not possess intrinsic worth. The powerful feelings of hurt and inadequately is felt early on in the life of a child. As he grows, the pain becomes more intense because the message is reinforced and the demand for performance becomes greater. Those who are fortunate enough to perform may fit in, but with a great deal of pressure which always keeps them on the edge of failure and rejection. As time goes on, the underdog compensates for his pain by making himself feel anger.
Anger feels better then hurt or inferiority.
The social order is predicated upon the issue of power. The underdog learns from society that through power of anger he can make the playing field level. Sad as it is, the playing field is level, at least for a while - everyone is hurting. Unless something is done to change the basic core values about the essence of human beings, it will happen again. The victims - the two young men will get the blame.
