Life in prison
In the novel Human Acts, Han Kang takes readers through prison life in Gwangju penal complex in 1990 to paint a picture of pain. Prisoners go through a lot of suffering at the hands of prison warders. In the novel, one prisoner accounts for what they go through. Firstly, prisoners receive harsh beatings frequently during interrogations. Secondly, prisoners do not get adequate food and medication while in detention. Thirdly, prison warders subject prisoners to harsh living conditions because they do not have adequate beddings and other necessities to sustain them in prison. When prisoners are released from prison, they suffer from depression, which leads them to alcoholism and suicide. For instance, when Jin-su is released from prison, he commits suicide.
