As a doctor, Sadao knew the value of human life. He risked his own life by saving the American sailor, even though he knew that he could go to prison for hiding a prisoner of war. He cleaned the Americans wounds, fed him and nursed him back to health. When the American was feeling healthy, he gave him provisions such as food and a boat, and helped him to escape from Japan. As a Japanese citizen, he fulfilled his duty by telling the General about the American. Even though the General forgot to send his assassins, Sadao could not be blamed for the American escape. Thus we can say that Sadao carried out his responsibilities, as a doctor, and as a Japanese citizen both.
