Edit: the reason he keeps crashing out and doing stupid bullshit is because he thinks once everything is said and done, the SK authorities are just going to slap him with a fine and deport him. That's literally the worst he believes will happen to him, because that's basically what Japan did with him. He has said as much on his livestreams. He doesn't believe that prison time is on the table at all. It doesn't help that in South Korea you typically don't get jail time until after your trial is over and the judge sentences you, from what I understand. So he's not getting held in jail until this is all over, which reinforces his belief that he will just get a slap on the wrist.
