Discuss the significance of the red dressed little girl in Schindler's List.

The girl with the red petticoat in the film is extremely
significant.  The first time that Schindler spots her from afar is when the ghetto is
being liquidated.  It is the first time that Schindler recognizes the horrors of the
Holocaust.  While he does not do anything in terms of massive action, Schindler's
conscience has been awoken and something in him has been sparked.  He spots this girl as
the only dash of color in a black and white world.  It is this moment of recognition
that serves to animate the actions that Schindler takes in favor of helping the Jewish
workers in his factory and bringing more into the factory.  The second, and final, time
in which Schindler sees the girls is when the mass extermination of people of the Judaic
faith is becoming policy.  Schindler recognizes the girl, only this time she is a
corpse.  The red petticoat still grabs him and this moment is what causes him to compose
the list and save his factor workers from the fate that awaits them.  The sight of the
dead girl now serves as a call to action, recognizing that the situation has become
impossible to deny what has to be done in the name of fellow human
beings.
