I think that's a very valid point by the GP. It's true that it's easier to kill someone when they want to die, rather than help them.

For some reason, mental/emotional problems are not treated differently from physical ones here, it's perverse. Some physical problems we don't have the technology to heal, allowing people relief from the pain they suffer from them is reasonable. But I'd wager the large majority of mental and emotional problems can be healed, given enough care, time and love.

But love is in short supply already, so may be that's not reasonable.
