What is the situational irony in "Young Goodman Brown"?

Situationaldescribes an
occurrence that is the
opposite of what we expect. In this kind of ironic situation what
actually
happens is so contrary to our expectations that it mocks our human intentions and
the
confidence we have in our ability to plan our futures and take control of
our lives. An example
might be a haughty rich man who will come begging from
us tomorrow, or a woman who is dreading
the party she is going to that night
but actually meets her future husband there.

In ""
therefore there is a whole load of situational irony. Goodman Brown
sees the
people he suspects least of having an involvement with the devil to be actually
witches
and involved in meeting with the devil. For example, Goody Cloyse,
Brown's "moral
advisor" has a conversation with the devil about a witch's
brew. Just at the point when
finally Brown decides to go no further so he can
face his minister and deacon with a clear
conscience, his minister and deacon
pass in a carriage discussing the meeting they are going to
have to worship
the devil. And of course, finally, his wife, Faith, is going to be at the

meeting too. How ironic!
