After the 5th or 6th time I said "you've got to be kidding?" while reading this column, I went in search of the back story. Wasn't easy, but this in the New Yorker is a long long read but takes one through a person's journey navigating the Belgian process.

Here is quote regarding the religious order mentioned above...

"René Stockman, the director of a Catholic organization, Brothers of Charity, which says that it runs a third of the psychiatric institutions in Belgium, told me, “They are using our Christian vocabulary in a new context. They say they are ‘saving’ people from their bad lives, through ‘mercy’ and ‘compassion.’ I cannot accept that.” He sees euthanasia as a failure of both psychiatry and medical education. “Any questions about ethics—they say, ‘Oh, we need a specialist for that.’ They are not learning to reflect morally on what they are doing.” What changed?

Just going to tag this one outta my pay grade.
