In Tolstory's "How much land does a man need" given the younger sister's last remark to her older sister, how is the appearance of the devil to tempt Pahom actually ironic?

Pahom, the avaricious Russian peasant of interest in this story, is never content with what he has, always desiring to possess more. He spends all of his effort in pursuit of more land and greater prosperity, devoting his life to the cultivation of this greed. This very dedication is his undoing, however; by exerting himself too much in his pursuit of land, he dies, making all of his effort vain, empty, and counterproductive. The point of the story is clear: greed never satisfies.
