Murder is when someone takes selfishness to the ultimate level and completely, irrevocably, and for all time takes someone else's life. This is often to take their possessions, sometimes just a wallet; sometimes their estate, sometimes to hide their identity as a rapist.... In short, murder is one individual stealing another person's entire life for some small benefit for themselves. It is the ultimate in disgusting.
Capital punishment is when someone has been deemed guilty and then is sentenced to be killed for crimes committed.
It is a right thing to punish the guilty and to defend those who cannot defend themselves. Society must enforce law. Only law and the prayers of the righteous keep wicked men at bay.
We must ensure that ignorant men know that evil knows no bounds, and they should not tolerate it- otherwise it might enter them. The law can keep fools out of crooked paths. Fear can protect them, and the victims that will never be.
