My instinct was to say "no, there wasn't a plan to kill" but then I stopped and thought a bit. And realized the Crown was right.
The imposition of malnutrition is not the same as the imposition of death. But both actions are based in the same mindset - the people "we" are dealing with are not the same as "us" and are lesser beings who can be used without regard for their inherent dignity and value. "They" are other and not fully or really human.
That view - the other is different and of no inherent worth - links the actions. It is a wicked view that ignores the sanctity of human life.
To be clear, the imposed malnutrition was an action of the Canadian government against Canadian children. It was racial based. It was of a piece with the German government killing German (and Polish and French and Russian etc) children. And as the Holocaust remains a trauma to this day so does the abuse of Canadians by their own government in the 1940s.
As Shawn Atleo of the Assembly of First Nations said, "The past isn't past. It remains with us to this day".
"For there to be reconciliation, there has to be truth."
