There were a murderer who had a car accident while trying to escape and a victim who was injured by the murderer, who would have to be saved by a drone? In this story, the drone would save a murderer because he had a higher possibility of survival than a victim. At that time, if a human determined who does he choose in this situation, he would not have made a rational decision easily. However, the drone can make a rational decision by choosing the best plan, because the drone is programmed, and can calculate the best way to solve the problem. I think that it can make a controversial situation. Some people believe that drone should have saved the victim instead of saving the murderer, but in the stance of doctors, they have instructed to save a person who has a high possibility of survival regardless of the personal information of the person.
