At what point in the story Young Goodman Brown does Goodman Brown abandon all faith?

Answer 1

Read this closely:

Young Goodman Brown is leaving his home when Faith, his wife, asks him to delay his journey until the morning. She doesn't want to sleep alone.

However, Brown demurs. This journey must be done before sunrise. He asks if she doubts him already after being married just for three months. She gives him her blessings and he leaves.
Faith Brown serves an allegorical purpose in this story. It is Faith that Brown leaves behind, presumably for one night, in order to keep his appointment with the Devil. Explaining to the old man why he is late Brown says, "Faith kept me back a while." She represents the force of good in the world.
Thus, when Brown perceives that she too has been corrupted, he shouts "My Faith is gone"' and rushes madly toward the witches's gathering.
The pink ribbons that decorate Faith's cap have drawn more critical attention than any other symbol in the story. On one hand they have been said to represent female sexuality, while on the other, innocence. Or, they may merely signify the ornament of a sweet and cheerful wife.
