A doctor who conducted a psychiatric evaluation of Mamoru Takuma, who was executed in 2004 for stabbing to death eight children at an Osaka school, will publish a book containing nearly the entire report, it has been learned.

The book — titled "Takuma Mamoru Seishin Kanteisho" ("Mamoru Takuma Psychiatric Evaluation Report") — contains statements made by the convict, such as "My life is weightier than those of hundreds of thousands of people," and "With only around eight (deaths), (the death penalty) doesn't pay. I can't accept it."

Takuma barged into Ikeda Elementary School in the city of Ikeda, wielding a kitchen knife on June 8, 2001, and stabbed to death eight children and injured 13 others and two teachers.
