Chun Doo-hwan retaliated because he couldn’t get support from his grandson.

(1)The possibility of religious delusion as if retaliating against Jeon’s family out of spite.
(2)Experts assume that Jeon made the revelation out of resentment and remorse for his family. Jeon was born in 1996 and reportedly moved to the U.S. when he was a student and grew up there, but he seems to have experienced various difficulties due to his father’s extramarital affair.
(3)Jeon claimed that he handed over billions of won in assets inherited in the form of company shares and stocks to his stepmother, Park, due to his father’s coercion. Jeon said, “My father lied and cheated on me because he was working abroad with Park while he was married to my mother. He invited me to the house where he lived with Park. He made me sleep on a bed he didn’t know what kind of behavior he would have shared.”
(4)Lee Soo-jung, a crime psychology professor at Kyonggi University, said, “I think there were many problems, such as my family not supporting me and my mother not playing a proper role in cancer surgery. I think the biggest reason for the revelation was that I didn’t want my father’s application for U.S. citizenship to be accepted.”
(5)Jeon said on the 13th that he was thinking normally and working hard, but he showed hallucinations after taking various drugs such as cannabis and LSD during a YouTube live broadcast on the 17th. Since then, the broadcast has ended as people who appear to be U.S. police dragged Jeon out.
(6)Throughout the broadcast, Jeon also used words such as angels and hell and made claims to the effect that he could judge people. Experts also raised the possibility that Jeon may have fallen into a so-called religious delusion as his drug dependence period has been prolonged. He was obsessed with the idea of confessing the crimes of himself and his family and being saved by God.
(7)Professor Lee said, “The name of Jeon’s YouTube channel is Jesus Christ,” and explained, “A religious scenario of confessing his fault and being saved is now possible. Among the delusions of grandeur that occur seriously by taking drugs, any delusion related to religion can occur.”
