"Young Goodman Brown" by Nathaniel Hawthorne

So I read this story 1 and a half times and still can't really get a grasp of it. I go the part where he had a vision and he thought that everyone was a sinner, but I couldn't help wondering if tha was the nature of the story. That everyone makes mistakes and everyone had secrets. I hope to find more about this story once I get to class today and maybe it will answer my confusion.
