devil in story

In this quote the Devil is giving himself credit for both sponsoring slave sales and prompting buyers to purchase those slaves. In context, he is putting himself at the center of all the evil acts the world has seen.

"Oh, I go by various names. I am the wild huntsman in some countries; the black miner in others. In this neighborhood I am known by the name of the black woodsman. I am he to whom the red men consecrated this spot, and in honor of whom they now and then roasted a white man, by way of sweet-smelling sacrifice. Since the red men have been exterminated by you white savages, I amuse myself by presiding at the persecutions of Quakers and Anabaptists; I am the great patron and prompter of slave-dealers and the grand-master of the Salem witches."
