dentify the central moral conflict of the play.

This is largely a thematic question. I might consider self-interest to be the main contriputing factor to conflict in the story. In varying degrees, the instigators of the witch trials are working to serve their own self-interest. Abigail begins the hysteria when she finds it a convenient way to deflect attention from her own sins, and further points the accusations at Elizabeth to scheme her way into Proctor's arms. Tituba, the first charged, is also the first to confess when she realizes that a confession will save her life. Parris at first rankles against the witchcraft talk because it would undermine his reputation in the town, and later opposes the execution of prominent community members because their death would lead to popular uprising. Even Giles Corey died in the way he did because it was in his own interest – by not pleading and dying under the weighted rocks, he ensured that his property would pass to his sons rather than to the state.
