why is reverend parris so terrified by the events in salem?

The first act establishes the primary characters of the play who instigate the Salem witch trials. Each has his particular obsessions and motivations that drive him to push for the trials. The first and perhaps most reprehensible of these characters is the Reverend Samuel Parris, a man who symbolizes the particular quality of moral repression and paranoia that drive the trials. Miller immediately establishes Parris as a man whose main concern is his reputation and status in the community, rather than the well-being of his daughter.
