Big Dog: The lawlessness that often accompanies a breakdown in social order can certainly make one wonder if humans are truly moral creatures.
That's an interesting point. Experience tells us that a surprising number of people will put aside their morals when faced with an opportunity to do so in apparent safety. This is especially true if the opportunity allows them some kind of moral 'wiggle room' (such as harming someone who is "deserving"). Our morality is almost never a black/white construct- it is wrapped in layers of understanding. Our community, our religious belief, our personal circumstances... all of these play a part.
Perhaps the real issue is the presumption that morals can only be rigid and inflexible. Almost no one treats them that way, with the probable exception of the ones with a solid consensus (murder or rape, for example). Admitting that morality is frequently pliable seems to be a non-starter for many religious believers, since they are certain that these rules come from god and are therefore strict regardless of severity.
