Question

Why miller felt the allegory was necessary?

Answer 1

Miller was particularly offended by those who "named names" before HUAC, and he himself refused to do so. While the Crucible indeed villainized the prosecutors and Court – those in the parallel positions of Joe McCarthy and HUAC – the play martyrs Corey and Proctor for refusing to do so. At the expense of their own lives, Corey and Proctor refused to condemn others, and in Miller's eyes, this is the only truly moral decision.
