O Hero, Trample Those Who You Should Protect!

TN: Most part of the other character in the novel is depicted from a non-human perspective so expect something that is completely different from the common sense of human.

Childhood, upbringing, family background, social relations, traumatic experiences…

We keep reviewing and seeking out the motives of criminals, exploring the subtlest emotions driving them. It’s not to put ourselves in their shoes and sympathize, or even forgive them; it’s not to find some reasons to exculpate their crimes; it’s not to kneel down before the so-called “complexity of human nature”; nor to introspect social conflicts, much less to alienate ourselves into monsters.

We just want to have a fair trial – for ourselves and for those who still have hope for the world.
