No worries - it took me a while to understand this point, too. People want it both ways - if there are no moral absolutes, then a person can do whatever he or she wants with their life and not feel guilty about it. But sooner or later, he or she finds themselves attempting to make a moral judgment about someone or something; they break their own #1 rule, "no moral absolutes," in order to get their own way.

This is why I hold to be true that moral absolutes do exist, and that the "amoral law" is illogical and untrue. Getting back to the original point, if there is a moral absolute, then there is a purpose in life after all!
