Comment by Hyacinthus2cents on Jinx - Chapter 76

I have read about people who are baffled by the fact that Jaekyung, despite his past, has become a bad and violent person, comparing him to Kim Dan and comparing their two characters (having had very similar pasts), considering this plot twist quite illogical, but in reality it is quite consistent if we think about the visible details or those that are implicit but can be perceived: First and foremost, which I don't think Mingwa is fully aware of, is genetics or the type of environment where the child had his first phase of development. Kim Dan has no blood relationship with his tormentors and, no less importantly, he had the love, support, and protection of his grandmother throughout his life to counterbalance the abuse and other traumas. For Jaekyung, the situation is very different and much worse: the abuser was his own father, and often, though not always, a child can inherit the violent temperament of a relative through genetics or assimilation: the victim can become the perpetrator. Kim Dan had his grandmother, who always showed him and taught him that there can be love in the world; that if you remain good, kind, and charitable, you will never lose your humanity, and your altruism will be rewarded with the gratification of seeing others happy. On the contrary, JK never had this kind of example. In fact, everything in his life taught him that love for others and for himself is useless, that in order to move forward with his head held high, he must rely exclusively on his own strength and use his violence as a weapon so that he can always win and dominate others without running the risk of being hurt again or losing to others, as happened in his past. In fact, the definitive rejection of his mother figure killed what little emotion remained in JK, making him feel betrayed and consequently causing him to develop distrust of others as well as anger and repulsion.
