If you kill a person, and then kill all the people who know him, and so on, how many people will be killed?

If you know this person, you have seen this person with your own eyes as the definition of knowing someone

Recommend an early anime Monster Monster

The basic operation of the villain in the anime is

Kill all those who know his enemies

Kill all those who know him

Kill all those who know His benefactor

All in all, his way of punishing and testing others is to create a social vacuum for each other

The social vacuum probably means that there is no one around the person who can prove and confirm that "he is himself."

For example:

The protagonist of the anime is the benefactor of the villain, and after the protagonist saves the villain's life, he witnesses a murder, but soon all the people who can prove that the protagonist is not the murderer die mysteriously

And people who have had conflicts with the protagonist are also inexplicably hung up

Even some people who are related to the protagonist will die unexpectedly (except for passers-by who do not know much about the protagonist)

Naturally, the protagonist becomes the only murderer in this large pile of murders, and then is forced to die

All in all, that anime is extremely frightening and very depressing, and it is recommended to watch it
