Good to see the manga acknowledge that the main character is hypocritical and insane. "if i kill someone its for justice, but if someone else does the exact same thing its just a crime". Most vigilante manga try to paint their main character as an anti hero.
@fanghue That's why I really like this series. I pointed the same out many chapters ago. Ji Young is deranged. The only thing protecting him from a moral breakdown is that he's very careful and thus hasn't killed or incapacitated anyone who wasn't truly "deserving" by his standards. The day he harms someone who's innocent or reformed, I doubt he'll be able to deal with it.
