I honestly don't know what the point of this drama is anymore. I thought it's about "writing past wrongs", but it's not really? With JC we had a glimpse of how terrifying his surroundings was and what affect it had in him, but with JB everything he does gets explained either like "he's a psychopath" or "oh it's a misunderstanding". If I could understand JC's motives, JB is like a caricature of a label.
I have no idea how they are gonna make a redemption arc for him. So far I just don't see it. Even if in this life he didn't actually kill anyone (unlike his previous one), he still attempted at least three murders, withheld information about a killer (which is a crime by itself), and then stalked and sexually assaulted his professor. So at this point I don't see any redeeming qualities in him.
