He is a genius scientist. He realized at an early age that this world was not worth living.He somehow struggled with what could be improved, but even a genius he found it impossible. So he decided to make a device that would destroy this world. He was a genius, so it was really easy. All you have to do is press the button.
However, he thought that it should not be decided by his discretion. The world does not belong to him, but to the people of the world. He thought so.
However, he did not appreciate the will of the people. From the perspective of a genius, people seemed unable to make the right decisions due to various beliefs and emotions. Just like looking out of frosted glass. It doesn't show the right image. Surely, if he declares that he will destroy the world, many will oppose it. But he thought it was just a sentimental decision. If people understand the situation right and think logically from it, they should know that this world should be destroyed.
So he made a device to persuade people. It's annoying to get wrong, but it's not like a brainwash that imposes his beliefs on people. It's a machine that lets people think, instantly understand objective facts, and then make logical decisions. He just wanted people to decide what they wanted to do with the world.
Using the device, people reached the same conclusion as him. I thought that this world should be destroyed and that living here is shameful. Some even killed themselves. The suicide note states that they cannot live in this world. He was hurt. Because he was a man who mourned the misery of others. So he decided to destroy the world. Can people be happy without removing the underlying misfortune? Even if it kills people.
Then, it seemed that the consensus of the world was shown. He also thought so until he pressed the button. But just before he pressed the button, he noticed that there was only one objection.
It was a little girl. The girl said.
"Please do not break the world"
He took a breath and spoke to the girl. The misery of this world. Those who die because of their poverty, those who are oppressed by the greed of others, those who are killed by so much loneliness, those who live without looking at them. The girl was listening to it.
"How about?" He told the girl. "Is it still better to not destroy the world?"
The girl nodded.
"why?"
"You may have seen them all, but I haven't seen anything yet."
"You don't need to see," he shook his head. "A miserable world"
"I will decide if I see them all. Don't decide by you."
He thought. The girl looks at him with straight eyes. Tears are gathering at the edges of the eyes. I'm sure it's irritating and scary. The man in front of her is the man trying to destroy the world.
"Okay," he said, offering the girl a launch button to destroy the world. "I will give you this. After you see everything with your own eyes, decide whether or not to press it."
Then he disappeared from the public.
The world has not yet been destroyed.
