why is john proctor in conflict with himself? describe the internal conflict proctor might feel

Proctor's conflict is the conflict of a man who wants to believe he is good inside and yet has committed an egregious sin in his society. While he tries to judge things on a rational basis, he has betrayed his wife and now is caught up in small lies about Abby and his meeting with her. He does not believe that the craziness that is affecting Salem would go so far; yet, by the time he actually convinces Mary Warren to talk about Abby's lies, the craziness has gone so far that nothing can be done. He disdains men like Parris and sees Putnam for the land grabbing man that he truly is.
