In both folktales, Jack only lets Satan go when he agrees never to take his soul. After a while the thief died, as all living things do. Of course, his life had been too sinful for Jack to go to heaven; however, Satan had promised not to take his soul, and so he was barred from hell as well. Jack now had nowhere to go. He asked how he would see where to go, as he had no light, and Satan mockingly tossed him an ember from the flames of Hades, that would never burn out. Jack carved out one of his turnips (which were his favorite food), put the ember inside it, and began endlessly wandering the Earth for a resting place. He became known as "Jack of the Lantern", or Jack-o'-lantern. @Curionic
