attitude of the world towards euthanasia

And now I want to tell you more specifically where euthanasia is prohibited or allowed. i want to start from North America.

 American’s Law Encyclopedia states that "a 'mercy killing' or euthanasia is generally considered to be a criminal homicide" and is normally used as a synonym of homicide committed at a request made by the patient.   

Canada. Suicide is not a crime but physician-assisted suicide is illegal. There are a lot of cases which are dealing with passive and active euthanasia in Canada.  However,   people like Francine Lalonde (MP) promised to legalize assisted suicide in Canada by private bills like Bill C-407.

USA. At first look, it looks like euthanasia is prohibited in all states of The USA. However, there are some exceptions. For example, assisted suicide or Physician aid-in-dying (PAD) is legal in the states of  Washington, Oregon, and Montana.

Mexico. Passive euthanasia is  legal in Mexico City and in two states: Aguascalientes and Michoacán. Active euthanasia is illegal, because General Health Law of Mexico still defines euthanasia as mercy homicide.

South America. There is only one country where euthanasia is legalized in Latin America. It is Colombia. In Colombia, euthanasia became permissible in 1997 when the highest judicial body, the Constitutional Court, ruled 6-3 that an individual may choose to end his life and that doctors can't be prosecuted for their role in helping. Euthanasia is illegal in all other countries of South America.
Europe.

There are only three countries in Europe where euthanasia is legal Netherlands, Belgium and Luxembourg. In 2002, the Netherlands passed a law legalizing euthanasia including physician assisted suicide. The Belgian parliament legalized euthanasia in September 2002. The country's parliament passed a bill legalizing euthanasia on 20 February 2008. However, there is one more country with not clear status regarding euthanasia. It is Switzerland.  Swiss penal code, considers assisted suicide a crime if and only if the motive is selfish.

Africa, Asia, Australia.

Euthanasia is forbidden in countries of Africa, Asia, and Australia.
