Jeju 4·3 Incident is state violence in which innocent civilians were massacred due to ideological conflict. This incident has caused great harm to individuals and communities. The aim of this study is to examine the trauma aspect of female victim of Jeju 4·3 Incident by analyzing the novel Sun-i Samch’on by Ki-young Hyun. Sun-i Samch’on, the protagonist of the novel, suffered from trauma until her death due to the aftereffects of physical, mental, and sexual violence caused by Jeju 4·3 Incident. Her trauma aspects were shown as nervous breakdown, auditory hallucinations, and obsessive-compulsive fastidiousness in relationships with others. The otherized trauma aspects prevented her from permeating into the community and made her unable to lead an ordinary life, leading to death. By doing this, this study shows that the victims of such state violence can be recovered if Sun-i Samch’on’s death is recognized as a problem for the whole community rather than an unfortunate death of an individual and extends the meaning of healing community.
