In modern society medical treatment has come a long way. Doctors now have the equipment and drugs available to them that can cure many different types of illness, or at least reduce the severity of the illness, for example by using painkillers to reduce the pain of an illness. Doctors also have the ability to keep people alive when otherwise they would have died, by using ventilators etc. While these people may be able to continue to live, they may have to do so in a great amount of pain. This raises the question of euthanasia, of which there is two types, active and passive.
