Did Young Goodman Brown make a good decision after leaving the forest?

I don't know that Goodman Brown really makes a decision to behave the way he does after he wakes up the morning after he spends the night in the forest.  Earlier in the story, Brown had made the decision to abandon his religious faith, represented by his wife, Faith, and embrace sin by going into the forest.  Although she begged him to stay with her, he would not, and he thought to himself, "'after this...

I don't know that Goodman Brown really makes a decision to behave the way he does after he wakes up the morning after he spends the night in the forest.  Earlier in the story, Brown had made the decision to abandon his religious faith, represented by his wife, Faith, and embrace sin by going into the forest.  Although she begged him to stay with her, he would not, and he thought to himself, "'after this one night, I'll cling to her skirts and follow her to Heaven.'"  However, this is not the way faith works; we cannot simply put it down and pick it back up again when it is convenient for us.  In making this decision, Brown essentially alienates himself from God; so, when he returns, "he shrank from the bosom of Faith" and becomes a "stern, a sad, a darkly meditative, a distrustful, if not a desperate man [...]."  He doesn't decide to become mistrustful or faithless.  It just happens as a result of the bad decisions he'd made earlier in the story.
