What are the darkest plots in anime?

I think dark plots are also very common in animation, and to say that the darkest plot I have ever seen, it is naturally indispensable. "From the New World", Yusuke Kishi set up a person A world where people cannot be attacked.

All people are genetically implanted with attack suppression and death-defying mechanisms. Once a person realizes that he has attacked the same kind, he will suffer from shortness of breath and heart palpitations at worst, and death at worst. Moreover, it also supplements the bonobo's group intimacy gene, thereby making people become close and loving, and it is simply a harmonious society.

However, the setting that people cannot attack others is not stable. Once there is a mental illness or genetic mutation, if you treat him as a human being, either he will kill you, or you will kill you. This means that if a person changes at a certain key point, he can no longer be considered a person. And this key point is the social relationship between people.

Humanity is a whole, and everyone is an individual in this whole. If someone destroys this relationship, he will inevitably be rejected. Some people have acquired magical powers, and those without magical powers will not be considered human beings. In other words, those with magical powers transcend traditional human existence and become superhuman. The curser tears apart the traditional human relationship, and naturally it becomes two relationship parts.

In order to stabilize their own collective, those with curses implanted themselves with death-shame mechanisms. Instead, people without curses became their nemesis, and social groups were once again defined and distinguished. The idea of ??setting people up to not attack other people is a good idea. The original intention is to eliminate the fighting between people, but in the end, it will still be full of killings, even more bloody. I hope my answer will satisfy the questioner. If you have any questions, feel free to ask or comment.
