I've come to the point in my life where psychopath killer can justified any wrongdoings in the story, in a certain point of view. I really like Dan, his didn't hesitate in everything he'd do. His resolve won't even waver if something happens. A very gruesome & brutal scene made by Dan and he even confess his sins in the church.
Brutal: Satsujin Kansatsukan no Kokuhaku
