Nor do the vast majority of civilized human beings. Or maybe I should say, nor does any civilized human being.Some people seem to have this misguided idea that someone's life is worth something simply because they are alive... I understand the legal system does not necessarily agree with my sentiment.
I'm not sure where such a profoundly misguided attitude may have come from, though I suspect that movies, TV, and shoot-em-up video games of the last 20 years may be a factor. Or at least, they can't have helped by trivializing the precious nature of life.
