We as a global nation try to hide the going's on behind a wall with only a select few allowed to witness the event of executing another of our own race. There was no question that everyone concerned knew this to be a dreadful unnatural action. It is probably the fact that capital punishment is accepted as necessary, and yet instinctively felt to be wrong, that gives so many descriptions of executions their tragic atmosphere. Executions have been said to have a deterrent effect on the crime of murder, although there is little to no evidence to prove this. The decision to kill another human is dependent on numerous different events that are in turn dictated by religion and beliefs.
Some countries use religion based government quoting their laws from the bible itself.
This verse from the Bible has been and will be used by the death penalty advocates to prove their point about the right of man to kill another man. All of us will die. The death penalty doesn't bring back the dead it just exacts retribution to the living. The innocent citizens search for a harsher more positive deterrent to crime than they did before to slay the ever rising wave of crime befalling our world. Saudi Arabia is one country that has boasted a deterrent effect from instating the death penalty.
