The Crucible tells the story of a man named Giles Corey who voluntarily offered a piece of information that would cause people to suspect his wife as a witch. He mentioned that when his wife read a book, he found it hard to pray but hen she stopped reading the book, he could then pray. This made people suspect his wife to be a witch. Through his actions, the author indirectly characerized him as a foolish man.
He tried to correct that impression when instead of giving the name of a man suspected to be wizard, he rather chose to die. The author through this description directly characterized him as a hero.
