Not sure about this guy being crazier you see...
It feels that way cause at least YJH felt bad about what he did and what he will have to do (regression depression and all that) but this guy dosent even care (￣∇￣")
Well, I still think YJH is crazier because even if this pseudo-hero's madness is there for us to see, as we can actually know the extent of psychological damage he suffered and the impact it had on his personality, it's easier to grasp his craziness. Whereas we don't have so much moments which portray YJH's mental state because we gradually become more aware of how fucked up his mind become because of reincarnation. And unless you are a novel reader who read past the novel mid-point, it's quite hard to define YJH as more than what he appears to be.
Wow I'm sorry for throwing that big of a response and it's still just my opinion since both character went through hellish traumatic experience and don't deserve to be defined as asshole (even though they ain't angel).
So this is how Yoo Jonghyuk felt with all the rounds of his life... except this guy is crazier then he is XD
