What stages of Kohlberg's Moral Development does Spielberg show in his film Schindler's List?

I think that, as a character, Schindler represents
different elements of Kohlberg's stages of moral development.  For example, I think that
the start of the film represents some of Schindler's demonstration of a pre-
conventional stage of behavior.  For Schindler, "behaving right" translates to making
money.  He struggled with this prior to his work in Poland during the Second World War,
hence his moral behavior code is governed by his embrace of how to make money and what
practices need to be done in order to profit.  Kohlberg's second stage of moral
development, addressing self interest, is seen when Schindler opts to use Jewish
laborers as opposed to Polish ones so that he can generate more money and amass more
personal wealth.  The conformist element in Schindler's behavior can be seen as he
befriends Nazi officials, such as Goeth, in his desire to make more money.  Yet, the
interesting element here is that Schindler acts in a socially conformist manner with the
Jewish population, as well.  He takes more Jewish people into his factory, gives them
more benefits, and shows them more benevolence, in general by permitting them to work
and allowing them to remain free from the clutches of the Nazis.  This is where
Schindler begins to advance in Kholberg's moral development, in that Schindler operates
in moral succession in parallel universes, it seems, until Schindler reaches a point
where he can no longer abide by what Nazi morality preaches, ascending to a moral state
of universality.  Schindler is able to do this, while still clings to the conformist
vision of the Nazis, and ascending to universalised conditions of morality at the same
time.
