Who are the foils in "The Lottery" by Shirley Jackson?

This is a fairly interesting question.  I think that if we
operate under the assumption that Tessie is the protagonist, one could argue that the
entire town is the foil to her.  The fact that Tessie is the outsider, the individual
who is chosen to be persecuted by the townspeople, she would be the foil to the
community, who becomes the antagonist in this setting.  It is slightly awkward to
consider the entire community to be the foil to Tessie.  However, in this, one
recognizes one of the most basic themes to the short story.  The idea of victimization
and persecution is a fundamental element of the short story.  In this theme, the
outsider is punished by the community, who operate as the insiders.  Tessie becomes "the
outsider" when her name is drawn and the community who take up stones to pulverize her
are the "insiders."  This would be why the entire community can be considered a foil to
Tessie.
