I think I have a passing understanding of cults and far-right and far-left terrorism.

I also know (from experience) the process by which personal anger can be justified within oneself and transformed into a murderous intent directed at a specific person.

In particular, the quantification and forgetting of anger emotions has been numerically modeled and incorporated into simulations under the (self-serving) name of the "Ebata Model".

After all, even now, I can give you three "real names" of people I want to kill.

However, I have no understanding of the recent indiscriminate killings at Odakyu, Keio, and the University of Tokyo entrance exams.

"What do they mean when they say they don't care who they kill? And what do they mean, "I want to be caught and sentenced to death"?"

I can't understand them.

In a word, it's not rational.

Of course, there are plenty of irrational negative emotions in the world (resentment, jealousy, vindictiveness, hatred, desperation, destructive impulses, etc.).

However, they are emotions that are shared in our society and also understandable from our own experiences.

And against terrorism and criminal acts caused by religion, ideology, or personal feelings as mentioned above, we can not only rely on the state security forces (such as criminal police (*1) or public security police (*2)), but also take some "preventive measures" by ourselves.

(*1) Basically, they investigate after an incident occurs.

(*2) Even before an incident occurs, they will continue to investigate organizations and individuals that may threaten the security of the nation.

But I can't think of any countermeasures that can be taken against terrorists who say, "I don't care who I will kill" or "I want to be caught and executed".

The persecution of Muslims as "reserve terrorists" by the United States, whose national policy is freedom of religion, is still ongoing.

Of course, this is out of line humanely (and probably legally), but I think the government of a security state would 'do this level of violence'.

In the case of Japan, through the efforts of the government and the police (infiltration as spies and intelligent counter-terrorism operations), they have succeeded in forming a national consensus (brainwashing?) that violent acts are unconditionally "evil, and the far left, far right and cults have been destroyed by them one after another.

(*) In this sense, I think the "Aum Shinrikyo case" is one of those cases that failed to be destroyed.

As a side note, I believe that in Japan, the concept that violence is unconditionally "bad" has been realized not through religion or ideology, but through "air", which is a characteristic that no other country has.
