In the 1930s, America was infatuated with the pseudoscience of eugenics and its promise of strengthening the human race by culling the "unfit" from the genetic pool. Along with the "feebleminded," insane, and criminal, those so classified included women who had sex out of wedlock (considered a mental illness), orphans, the disabled, the poor, the homeless, epileptics, masturbators, the blind and the deaf, alcoholics, and girls whose genitals exceeded certain measurements. Some eugenicists advocated euthanasia, and in mental hospitals, this was quietly carried out on scores of people through "lethal neglect" or outright murder. At one Illinois mental hospital, new patients were dosed with milk from cows infected with tuberculosis, in the belief that the undesirable would perish. As many as four in ten of those patients died. A more popular tool of eugenics was forced sterilization, employed on a raft of lost souls who, through misbehavior of misfortune, fell into the hands of state governments. By 1930, when Louie was entering his teens, California was enraptured with eugenics, and would ultimately sterilize some twenty thousand people.

Mutsuhiro attended Tokyo's prestigious Waseda University, where he studied French literature and cultivated an infatuation with nihilism.

Few societies treasured dignity, and feared humiliation, as did the Japanese, for whom a loss of honor could merit suicide. This is likely one of the reasons why Japanese soldiers in World War II debased their prisoners with such zeal, seeking to take from them that which was most painful and destructive to lose. On Kwajalein, Louie and Phil learned a dark truth known to the doomed in Hitler's death camps, the slaves of the American South, and a hundred other generations of betrayed people. Dignity is as essential to human life as water, food, and oxygen. The stubborn retention of it, even in the face of extreme physical hardship, can hold a man's soul in his body long past the point at which the body should have surrendered it. The loss of it can carry a man off as surely as thirst, hunger, exposure, and asphyxiation, with greater cruelty. In places like Kwajalein, degradation could be as lethal as a bullet.
