The fact was that, while Misty was moral, Vincent was good. Watching him sleep it was revealed to Misty that the good do not necessarily have to maintain morality: they are born with it, while people like Misty, who were not good, had to strive mightily for goodness. That was what a moral system was: it helped you be good when you weren’t very nice. From Vincent, Misty learned that goodness and stupidity were not necessarily linked. You could be good and smart.
