In Chapter 15 - "Hester and Pearl," Hester confronts Chillingworth as he gathers herbs, which she suspects are no longer healing but of the poisonous, killing kind. Chillingworth is untrue to the helping creed of medical people.
So Roger Chillingworth--a deformed old figure, with a face that haunted men's memories longer than they liked--took leave of Hester Prynne, and went stooping away along the earth. He gathered here and there an herb, or grubbed up a root, and put it into the basket on his arm. His gray beard almost touched the ground, as he crept onward. Hester gazed after him a little while, looking with a half-fantastic curiosity to see whether the tender grass of early spring would not be blighted beneath him, and show the wavering track of his footsteps, sere and brown, across its cheerful verdure. She wondered what sort of herbs they were, which the old man was so sedulous to gather. Would not the earth, quickened to an evil purpose by the sympathy of his eye, greet him with poisonous shrubs, of species hitherto unknown, that would start up under his fingers? Or might it suffice him, that every wholesome growth should be converted into something deleterious and malignant at his touch? Did the sun, which shone so brightly everywhere else, really fall upon him? Or was there, as it rather seemed, a circle of ominous shadow moving along with his deformity, whichever way he turned himself? And whither was he now going? Would he not suddenly sink into the earth, leaving a barren and blasted spot, where, in due course of time, would be seen deadly nightshade, dogwood, henbane, and whatever else of vegetable wickedness the climate could produce, all flourishing with hideous luxuriance? Or would he spread bat's wings and flee away, looking so much the uglier, the higher he rose towards heaven?
"Be it sin or no," said Hester Prynne bitterly, as she still gazed after him, "I hate the man!"
