Think about it: the absence of lying must also means the
absense of morality. The fact that he couldn't go through with
sleeping with the blond lady based on a lie means he didn't
only invent lying but morality as well. But how could he have
known morality without first kowing guilt, and how could he
know guilt without first committing the sin and experienceing
it's consequences, and without all of this how could he have
had the foresight that the act would have been wrong before
committing the act... It was all just too much of a stretch for
me to make. I thought the movie was flawed, and ultimately
those flaws proved fatal.
