What are some internal/external conflicts in "The Minister's Black Veil"?

There are many conflicts within this classic story. The first is between the minister and his congregation. He dons the veil, and this clashes with their needs and expectations. This is directly related to a conflict between good and evil, at least in the eyes of the townspeople. Think of how the old woman swears the corpse shuddered when the veil dropped; the veil is so disturbing it creates a conflict between life and death, and between stages of reality. Conflicts spread, as when a boy imitates the minister and scares his friends.
