At the same time, the laws of a society do not provide the spiritual bread necessary to sustain a society that hungers for spirituality. In other words, man does not live on bread alone. Stated differently, most societies have a certain internal duality; most of the time, people go about their regular lives dealing with such necessities such as school or work. However, occasionally, whether it be a holiday (derived from Holy Day) or simply that odds are that the sabbath recognized by your religion falls squarely during the weekend, a time during which most people are not working, provides an opportunity for people to behave less materialistically and more maternally. During this down time, people are free to do whatever they need to unwind, to recharge, or to refocus.
By the way, from a semantic standpoint, there is no such thing as justified or justifiable murder.
When one person kills another person, whether it is justified, such as in self-defense, or whether it is wholly unjustified cold blooded murder with malice aforethought, they may both be called homicide. To use a more specific word requires that we distinguish between whether the killing was legally justified. If the killing is not legally justified, then the proper term to use is either murder or manslaughter, depending upon the intention of the actor. In contrast, if the killing is one which modern law deems wholly justified, the correct term is justifiable homicide.
