[Department of Psychology] What is Defendant Aoba's true aim? - Kyoto Animation arson murder case - Until the 9th trial of the first trial -

The trial began in September for the 2019 incident in which Kyoto Animation Studio 1 was doused with gasoline and set on fire, killing 36 people.This time, we will look at the trial records up to the 9th trial and reconsider the defendant's motives.

Defendant Aoba graduated from a part-time high school with perfect attendance and entered a vocational school, but dropped out.Since then, he has been working various non-regular jobs, such as working as a convenience store clerk.His work style could not be called serious, and even when his superiors warned him about it, he would take time off from work or act defiant.On the other hand, he was said to have yelled at his juniors over trivial matters, causing several of them to quit their jobs. ing.Due to his unstable job, his life was so poor that his electricity and gas were cut off, and he was arrested twice for theft, assault, and robbery.After serving three years in prison, he was released and received welfare, but he lives alone and often gets into trouble with his neighbors.As mentioned above, his inability to build good relationships with others seems to be due to his distrust of humans and strong suspicion stemming from the severe abuse he suffered from his father when he was a child.

In his 30s, the defendant was moved by a KyoAni movie, so he wrote his own novel and submitted it to the KyoAni Grand Prize, but he was not selected.Originally, the defendant is the type of person who overestimates his own abilities, so he was deeply hurt and dissatisfied when his work was not selected as an excellent work.The defendant puts aside his own incompetence, and takes the blame for his disadvantaged life because KyoAni did not accept him.He begins to have a delusion that he blames a "dark figure" for his work not being selected, and thinks that Kyoto Animation has stolen some of the great ideas that were scattered throughout his work. It becomes like this.By doing so, he not only gained a sense of self-affirmation, but also argued that his resentment toward Kyoto Animation, who plagiarized the work, was a rational motive for the arson murder.Therefore, the defendant did not think that his novel had been plagiarized after seeing KyoAni's new work, but rather that he had a preconception that it had been plagiarized, looked at the work again, and decided that his work had been stolen. It is assumed that there is no such thing.At trial, the defendant's submitted work was compared with relevant scenes from Kyoto Animation works that he claimed to have plagiarized ("Free!," "Tsurune," and "K-On"), but as a result, the defendant's delusions, accusations, or It seems that most of the jurors had the impression that this was nothing more than a hunch.

Another point that caught my attention in the statements made during the trial was that about a month before the KyoAni Incident, the defendant brought six kitchen knives to JR Omiya Station near his home and committed an incident of indiscriminate mass murder. That's what I tried to do.Regarding this point, he said, ``By causing a fuss, I wanted to stop KyoAni from plagiarizing the work.''However, even if the defendant caused the incident at Omiya Station, KyoAni would not think that it had anything to do with their company.The defendant then stated that he gave up on carrying out the plan because he thought, ``There's not much density at Omiya Station, so it won't cause a big fuss.''Given this background, it seems likely that his true motive was to cause a big commotion and focus the world's attention on himself, in other words, to satisfy his desire for approval.

In this column, we will discuss the incidents that have occurred so far that attempted to commit indiscriminate mass murder (such as the arson of a clinic in Osaka Kitashinchi, and an attempt to set fire to the inside of a train on the Odawara Line and Keio Line by pouring oil on it). I explained that there was a desire for approval.This point is similar to the Ikeda Elementary School Incident (Mamoru Takuma, 2001) and the Akihabara Incident (Tomohiro Kato, 2008).In other words, they blame others for their failures and setbacks (a tendency to blame others), and take revenge on a society that overestimates their abilities and takes their long-term frustrations into account. An incident that kills many people at once.This time, rather than mass murder, as an anime work, the idea is to make Kyoto Animation, which is a symbol of success and a target of admiration worldwide, disappear from the world in one package to make one's existence stand out. It is possible that this was the purpose.In the background, narcissistic personality disorder and antisocial personality disorder can be felt.
