MTL - Conan’s Magical Girl - Chapter 68

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

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.
