If like that then there should be no depression..we all adults we should know how to behave no?
This comment makes no sense. Depression occurs because of the irregularity in your brain chemistry like serotonin and dopmaine leading to low moods leading to more reclusive behavior. Jaekyung is bad behavior is him making those choices and even if its trauma, he is aggressive and has now become the abuser and how he treats Dan. Horrifying what happened to him as child but not excuse for how is behaving as adult especially if he has done nothing to address his trauma.
How would he address it tho when no one point it out? He living just like that since age..making him a boxer just feed up to him being just like his dad..tho at least..he didn't go down to being drug addict and a mob..
Lots of his team membes and coach have told him about his ungrateful and aggressive behavior. He was even slapped for it after he lost his fight. Agreed that the world he is in feed into it. But again still a red flag and needs to take accountability for his actions.
Your circumstance, no matter how bad it is, is not an excuse for your behavior as an adult. When you become an adult, your brain develops and you know how to behave. So, bad circumstance does not equate to bad behavior.
