Anger cannot be the sole and simple culprit. Many writers have since wrestled with an answer. I have read numerous commentaries that link the deterioration of our school system and youth to the removal of religious references to God, prayer, the Ten Commandments and a code of discipline. While many may dismiss these concepts as narrow-minded and antiquated, it is important that we do not throw out the proverbial baby with the bath water. Indeed, from a secular perspective, it could be argued that the gunmen's' destruction truly resulted from a lack of values, morals and conscience.
Values are standards that have some intrinsic or estimated worth.
Values are the ideas, beliefs and things we hold true and precious. We deem these values worthy of protection and preservation. In this case, the values have to do with the sacredness of human life, the interconnectedness of living beings, personal responsibility, civility, freedom, truth, choice and tolerance. It is our values that inform our morality. Morality is our system of knowing what is right, true and expedient from what is wrong, counterfeit and destructive.
