According to Miller, Reverend Hale is almost forty years old and is a "tight-skinned, eager-eyed intellectual." He is very proud of his craft (career) of witch-hunting and is excited to finally put his skills and years of learning to use. He considers himself a specialist on witches, although he has never seen one first-hand. The only allegedly witch he has encountered turned out to be innocent. Despite this setback, he is certain that witches and evil exist and that they can be proved through science: "We cannot look to superstition in this. The Devil is precise."
Regardless of his initial over-zealousness, Hale proves to be a scrupulous and just man, as he demands that the innocent be let go when he realizes that the trials are a mistake.
