Becoming a demon isn’t a transaction. It means achieving what you desire in the purest, most violent way.
Those who become demons see the world differently from ordinary people. In their eyes, every human disguise is stripped away and people become animals: abusers are hyenas, wolves, and bears; bullies are monkeys and crows; indifferent bystanders are sheep, cows, and donkeys; hypocritical authorities are pigs and foxes; the kind but powerless are Buddhas and Bodhisattvas; and the domesticated are cattle and horses. Those who become demons cannot see their own shape. They are merely a mass of “nothingness.”
