In this study, I have analyzed the relationship between the problem of the evil and the Korean classical novels, especially focussing on the theodicy and the Confucianism. The purpose of this study is toconfirm the problem of evil should be an important subject in the Korean classical novels and to make a general survey it. Over the long term, the existence and origin of evil have challenged the Christian faith to God regarded as the being of the omniscient, omnipotent and infinitely good. Because the confucianists including Mencius(孟子) and Zhuxi (朱熹) have considered the human nature was fundamentally good, the origin of evil has not been seriously inquired in the Confucianism. The confucianists have regarded novel as a tool for the edification which could make human nature good like taken off blind from eyes. In thisstudy, I supposed that these differences between the theodicy of Christianism and theory of natural goodness(性善說) in the Confucianism have to been seriously considered in the study of Korean classical novels. In chapter4, I have outlined the problem of evil in Korean classical novels as four dimension, the narrative inquiry on the origin of evil, the narrative edification of human nature, the overall research of the evil characters and narrative plot, and the cross-cultural understanding to the property of Korean evil.
