Summarize Hale's view of his mission to Salem.

When Hale enters Act I, scene 3 with a great amount of
books and asks for help in putting them down, it is reflective of how he sees his
purpose in and mission towards Salem.  Hale sees his purpose as ridding the town of
witches and the presence of the devil.  He believes that the town is genuinely in need
and will commit all necessary resources and attention to this end.  Hale does not
recognize that the devil "walks amongst" the townspeople and is a charge used to
consolidate power.  Hale's mission is antithetical to this.  He sincerely believes that
evil exists outside of the individual and through this end, he is committing all his
ends and energy in order to make this a reality.  Hale believes that Salem is a town in
need of his energy and commitment towards ridding them of witches and the devil.  This
energy is apparent when he seeks to extract a confession out of Tituba.  Over the course
of the drama, this commitment lessens as he realizes the real character of the
townspeople.  Yet, from the most initial of points, Hale believes that his mission is
one whereby the town is in need of his efforts in eliminating the presence of witches in
the town.
