Perhaps I got you wrong, but what you are talking about is not "euthanasia" as leaglized in the above mentioned countries.
When you have a look at the Dutch law
" [...] The due care criteria which must be met in order to obtain exemption from criminal liability require that the attending physician:
be satisfied that the patient has made a voluntary and well considered request
be satisfied that the patient's suffering is unbearable, and that there is no prospect of improvement
has informed the patient about his or her situation and prospects
has come to the conclusion, together with the patient, that there is no reasonable alternative in the light of the patient's situation
has consulted at least one other physician, who must have seen the patient and given a written opinion on the due care criteria referred to above, and
has terminated the patient's life or provided assistance with suicide with due medical care and attention. "http://www.aph.gov.au/library/pubs/rn/2000-01/01RN31.htm
you'll notice that no-one else than the patient himself is concerned to this.
The last chapter from the above quoted website seems to be the most important facts to me:
"The enactment of Netherlands legislation represents the culmination of almost thirty years of public debate in that country about legalising voluntary euthanasia. The nature and result of that discussion has been influenced by an arguably unique combination of social and cultural factors:
a willingness to discuss difficult moral issues openly
a profound respect for the autonomy of others
the Royal Dutch Medical Association's approval of doctors participating in termination of life on request or assisting with suicide
respect for the medical profession, and
truly universal and comprehensive medical coverage.
