There absolutely have been pretty well publicized cases of people with no intention of dying being counseled to consider death - this is problematic. There's also the fact that when your treating doctor starts suggesting euthanasia, and there are very very low bars to qualify for this, then that is going to have an effect.

I don't know your father in law's condition, perhaps he was someone who genuinely would have benefited from less months of life, or perhaps he simply didn't receive the best care to manage his condition as he reached the end - and if he was experiencing unmanaged pain as it sounds like from your description, then that would absolutely be the case. In any case, MAID was responsible for 5% of Canada's deaths last year alone... and as of next year, simply being mentally ill will become a fully qualifying condition - there's something badly wrong with what's happening.
