Because:
1. everyone sees the world in their own way + no one knows the truth;
2. the cause of any decision a person makes is perception, which was shaped by the structure of society, not independently by the person.

Therefore, morality is a fictional category that distorts perception.

It teaches you to label people and things and divide the world into black and white before you even become aware of it. As a result, a person:
- does not live their own life (because they use imposed scripts rather than forming a personal view of what is happening);
- makes the least beneficial choices, since they take less context into account.

The thing is, nearly all communication is structured around morality – both direct, such as conversations, and indirect, such as films, fairy tales, advertising, etc. People have been labeling things for thousands of years, while none of this exists in life:
- good and evil, honor, justice, dignity, vice, mercy, etc.
- hero / antihero, brave / coward, talented / untalented, champion / loser, altruist / egoist, loyal / traitor, etc.

In other words, society’s understanding of life is deeply distorted.
