In Chocolat, to what extent does Vianne influence social and cultural norms; to what extent is she affected by traditions and societal expectations?

In Chocolat we have some conflicts
going on. Life in the small French village is dominated by the Catholic Church, led by
Francise Reynaud. When Vianne shows up, it is Lent, the 40 days before Easter Sunday,
when Catholics are supposed to concentrate on their sins, realizing that Christ was
crucified for them, and give up some pleasurable thing as a mini-sacrifice, to join in
Christ's sacrifice. Lent is a somber time and people are supposed to be somber, until
Easter, when they can rejoice again, because Christ rose from the dead. These are the
traditions that Vianne encounters when she arrives in
Lansquenet-sous-Tannes.

Vianne is a free spirit whose
grandmother might even have been a witch. She believes in joy, pleasure, and the symbol
of joy and pleasure is her chocolate. To Reynaud, however, chocolate represents sin
because the people are tempted by it, in spite of the fact that it is Lent. He thinks
that Vianne is leading them further and further into sin. The societal expectation in
this town is that one should not eat chocolate during Lent, so when Vianne tempts the
people with just the right kind of chocolate, and when she puts these tempting pieces in
the window of the shop, Reynaud thinks she is doing the Devil's work.
guilt is a big part of the traditions in this town and
Vianne is obviously free from this tradition because she is an
outsider.

It is the outsiders that bring the joy of life
into this town -- both Vianne and Roux and his gypsies. I think the point of it is that
the church's traditions have resulted in only somberness,
with no joy, and that is not how God wants people to
live.
