Hmm, this is a difficult subject.
Who are we to determine who deserves to live?
As we certainly don't go around raising the inanimate bodies of those we consider died too young, neither should we have any say on whether or not the living should meet the kiss of death(HURRAY FOR LONG SENTENCES!).
Sometimes, when our loved ones die in the hands of merciless murderers, we are quick to think of revenge. We shout "execution!", tossing the word in so many ways and in so many different places that the sound makes us not only deaf, but also blind and stupid. We forget that omniscience belongs only to deity, and we act; we connive, sue, slander, appeal, sympathize, hate, love, and pity, all without any genuine reason. We fail to see and comprehend the silliness of acting for those who have passed on to a possibly better life.
Besides, who in the world knows what the dead really want? Perhaps the only thing they want is for their names to rest, so that existence no longer echoes through their bones.
I believe execution should not be handled at all. We are certainly going far enough punishing those we merely know (even if it is for the 'betterment' of society).
