There are no villains in the piece. Crime, like disease, is not interesting: it is something to be done away with by general consent, and that is all about it. It is what men do at their best, with good intentions, and what normal men and women find that they must and will do in spite of their intentions, that really concern us. The rascally bishop and the cruel inquisitor of Mark Twain and Andrew Lang are as dull as pickpockets; and they reduce Joan to the level of the even less interesting person whose pocket is picked. I have represented both of them as capable and eloquent exponents of The Church Militant and The Church Litigant, because only by doing so can I maintain my drama on the level of high tragedy and save it from becoming a mere police court sensation. A villain in a play can never be anything more than a _diabolus ex machina_, possibly a more exciting expedient than a _deus ex machina_, but both equally mechanical, and therefore interesting only as mechanism. It is, I repeat, what normally innocent people do that concerns us; and if Joan had not been burnt by normally innocent people in the energy of their righteousness her death at their hands would have no more significance than the Tokyo earthquake, which burnt a great many maidens. The tragedy of such murders is that they are not committed by murderers. They are judicial murders, pious murders; and this contradiction at once brings an element of comedy into the tragedy: the angels may weep at the murder, but the gods laugh at the murderers. The Inevitable Flatteries of Tragedy.
