Carrie is a doctor working in a hospital. Due to an accident in the building next door, there are deadly fumes rising up through the hospital’s ventilation system. In a certain room of the hospital are four of her patients. In another room there is one of her patients. If she does nothing the fumes will rise up into the room containing the four patients and cause their deaths.

The only way to avoid the deaths of these patients is to hit a switch that will cause the fumes to bypass the room containing the four patients. As a result of doing this, the fumes will enter the room containing the single patient (against her will). If she does this, the woman will die, but the other four patients will live.

Should Carrie hit the switch in order to save four of her patients?
