Hale was needed in Salem as he was labelled as a ‘spiritual doctor’ who could diagnose the presence of witchcraft and to demolish its presence from any town. As witchcraft was assumed to be present around Salem, Hale had stayed and took part of the ongoing witch trial. Hale was a second voice to the court and many admired him and his work. I assume that Reverend Parris was quite interested in Hale by the way he had acted in his first meeting with him. Although he was a young doctor, Hale had an increasing reputation among Salem and was respected within the community. When the witch trials began, he would not condemn anyone without investigating, proving that they are indeed a witch but the expectations from the people in Salem overwhelmed him.
