To what extent are we as readers asked to agree with the devil's speech about being "the nature of mankind"?

In the story,
Hawthorne presents sin as part of human nature, no one escapes it, not the minister, not the
high members of society, and even not his wife Faith, whose very name symbolizes the absence of
evil. TO that extent, I think Hawthorne has a really strong view in the isolation of human
spirit, shown by the way Brown ends up.I think that Hawthorne wants the reader to believe in the
devil's speech.
