A Korean student's depression contributed to his sickening rape of a Figtree woman but not to the extent that he was unaware of what he was doing, a court has heard.Forensic psychiatrist Dr Stephen Allnutt yesterday told Wollongong District Court that Korean national Jung Hu Park, 22, was strongly driven by emotion when he broke into the woman's room on February 27 last year, armed with a knife and rope.Threatening to kill her if she screamed, Park tied the woman's hands to her neck before sexually assaulting and raping her.He also taunted her through the prolonged attack by reading a pre-prepared list of reasons why he wanted to kill her, but said he would give her tips on how to survive because he loved her.Park videotaped the ordeal, threatening to post it online and send it to her family and friends if she spoke out about the attack.He pleaded guilty to two charges of inflicting actual bodily harm on the woman while having sexual intercourse without consent.During a sentencing hearing yesterday, Dr Allnutt said there was some connection between Park's depression and the offence, and while his illness did not amount to psychosis, it did affect his judgment.Defence barrister James Trevallion described his client as a particularly young and naive man who was culturally isolated."He has no access to other Korean people in custody, no family or friends close by ..." Mr Trevallion said.When questioned in the witness box, Park said he understood what he did was wrong and that he had hurt the woman.Director of Public Prosecutions lawyer Kristy Spiers said there were a number of aggravating features in the case, including the presence of a knife, the death threats, duration of the attack and the degree of planning involved.She also said the multiple sexual acts further degraded and humiliated the victim.Judge Paul Conlon reserved his judgment until April 15.
