Nam Gon, and Shim Jung, except for a petition by three Seunggyungwan students (as opposed to 300 who petitioned for his release). Nam Gon rather urged against executing Jo multiple times even as he was adding more and more names to the list of people to be purged through exile or dismissal. Yet Jungjong turned against Jo with the same intensity as when he favored him. He reinstated death sentence by poison for Jo less than a month after their exile. He fired many ministers who entreated on Jo's behalf including Chief State Councillor Jeong Gwang-pill, Deputy State Councillor Ahn Dang, and even War Minister Yi Jang-gon, who took part in arresting Sarim officials. Jo Gwangjo still could not believe Jungjong's heart really turned against him and hoped to be recalled by the king, keeping a north door open each day during exile. Even when soldiers arrived with poison, he was suspicious that Hungu leaders might be trying to kill him without Jungjong's approval. But when he learned that Nam Gon and Shim Jung became Vice State Councillor and Minister of Personnel, he finally realized that Jungjong's change of heart was final. Before drinking the poison, Jo wrote a poem declaring his loyalty, asked his people not to make coffin too heavy, and apologized to the owner and servant of the house for not paying his debt and instead showing them terrible sight and desecrating their house. He then bowed four times toward the north in the direction of palace. (It was customary to pay respect to the king in gratitude for granting poison, which was not an official method of execution and was considered more honorable form of death, instead of beheading or hanging.) When he drank poison, he did not die immediately and soldiers tried to strangle him. Jo rebuked them saying that the king intended to spare his neck by sending the poison and requested for another bowl of poison. He died at the age of 37. Later when there was a severe drought in the country, the populace blamed that it was heaven's punishment for killing an innocent seonbi. Many of remaining Sarim scholars left the central government in protest and retreated to rural provinces. Most of Jo's reforms were revoked with his fall. The Third Literati Purge of 1519 (기묘사화 己卯士禍) was widely viewed as a missed opportunity to reform Joseon Dynasty by later generations
