Active euthanasia, unlike passive euthanasia, causes the death of a person through direct action. It is done in response to the request of a suffering individual. The patients need not be terminal, but are usually in excruciating pain and have no will to live. A very famous example of active euthanasia was Dr. Kevorkian’s 1998 mercy killing of Thomas Youk, which was aired on 60 Minutes. The doctor himself injected Youk, who was suffering from ALS (Lou Gehrig’s Disease), with the death-inducing substances.
