I come from a country which just legalized euthanasia and part of the safeguards we have is to try to be very sure that nobody takes it because they're suicidal due to depression. That might not be truly fair since some people might really be suffering that badly from it, as you say. But I came into this discussion with the prejudice that depression was an important reason to deny suicide assistance and the article gives an example of somebody who apparently died because of it.

You seem to be more open minded and consider depression might be an acceptable reason for doctors to kill their patients on request, if the patient really really wants it?
