@maxdancona,
Well that's simply not correct.
First of all there aren't multiple Western Civilizations there is one Western Civilization, and unless you've decided which Western nations are legitimately representative of the whole, the current laws of one nation versus others are hardly definitively of the mores of Western Civilization.
Western nations don't place the value of any human life above the life of another species. America certainly doesn't. If it did we wouldn't have American farmers in California being crippled by edicts established by our government to protect smelts.
How have you come to your conclusion?
Western Civilization has never held the lives of brutal murderers in high esteem. That some now feel it more "civilized" to place them in a cell for the rest of their lives rather than killing them is hardly indicative of any actual moral consideration.
Capital punishment is a political consideration. The State shouldn't have the power to kill any of its citizens, but this has nothing to do with effete notions of civilization.
Not to mention how hypocritical it is for people to unconditionally sanctify
human life, irrespective of the sensible consequences of human behavior, and yet champion the freedom to exterminate the most innocent of human lives.
