Oh Sangwoo, the antagonist of the psychological horror manhwa Killing Stalking, exhibits a highly complex and deeply disturbed personality characterized by traits of psychopathy, severe trauma, and the cycle of abuse.His personality is split into two distinct sides:The Facade (The "Nice Guy"): In public, Sangwoo is universally charming, cheerful, handsome, and extroverted. He uses this gentle persona to maintain a large social circle, seduce his victims, and lower the guard of those around him.The True Self (The Sadistic Killer): In private, he is cold, calculating, and ruthlessly violent. He displays no empathy and is a master of psychological and physical torture, often manipulating his victims before murdering them.Key Psychological Traits:Extreme Sadism: Sangwoo derives immense pleasure from inflicting physical and mental pain, often using his victims to reenact the trauma of his childhood.Narcissistic and Antisocial Tendencies: He displays classic signs of Antisocial Personality Disorder (ASPD), including a total disregard for the rights of others and a lack of remorse. He views others primarily as tools or toys.The Cycle of Abuse: Sangwoo's personality is deeply rooted in his horrific upbringing, where he suffered severe abuse and manipulation from his parents. As a result, his interpersonal relationships are highly volatile. He frequently oscillates between sudden fits of rage and "love-bombing," which keeps his captive, Yoon Bum, in a constant state of confusion and dependency.Need for Control: He cannot stand to be disobeyed or trapped, lashing out with intense hostility and physical violence when he feels threatened or aggravated.
