To understand Kougami means to think the way he does. To see the world through his eyes. <...> "When you gaze long into an abyss, the abyss also gazes into you." Kougami stared into the darkness for too long. And he's still staring into it even now. Maybe for him, the only true justice in the world exists solely in the depths of that darkness.
— Do you and Kougami want to be heroes that badly?!
— It's not about justice. It's an obsession. Even though you know there are other, wiser ways to live, you feel that if you turn your back on everything you've worked toward, it's like admitting you lived a lie. <...> This is because of our pride as men.
Do you think that's irrational? But you know, our line of work is full of things that don't make sense. What a person thinks or what he hopes for... We're in a time where everything in the human mind can be read by machines. And yet there are still people who would hate, fool, and try to harm others. If that's not irrational, then what is?
— Oh, there's our man. On the right, hiding behind the front column.

Today's generation isn't tolerant against stress, so they're susceptible to violent impulses and obsessive compulsions.
