The human brain is designed to look into the future, but with limitations. The only certainty that exists in life is that everyone dies; but despite this, the brain hides it for fear of maddening its bearer. This truth usually emerges from time to time as a "Fear of death". The fear that that moment will come and that there will be neither present nor future ends up being inevitable. The way it arrives adds uncertainty and horror: will it be sudden and painless? quick and cruel?

This book addresses the terrifying, violent, and bloody deaths through historical records to the present day, to understand their causes and origins, and understand where the human race is in the conception of its finitude.
