Was the plot in Schindler's List believable?

I actually think that much of the answer to this question
lies in whether one believes in the power of human redemption or if there is a
predisposition to deny that these transformations are possible.  The fact that the story
or plot is historically valid indicates that believability is more of an issue of
personal temperament and personal disposition more than anything else.  If an individual
does not believe in Schindler's transformation and evolution into a virtuous man, then
there is a greater likelihood that the change is not necessarily believable.  The larger
issue might be how one views human nature.  The Holocaust was a time when most theories
that ascribed negative qualities to human consciousness were sadly proven true.  The
theories that gave human beings some level of credit for being honorable creatures or
for representing healthy notions of solidarity or community were strained.  Yet, there
were examples of individuals who upheld such beliefs.  Schindler would be seen as one of
them.  In the end, the plausibility of the script has to comes down to how an individual
views such a paradigm.
