And yes, that Chesterton quote has to be the most asinine thing I've ever read anyone say about this subject, ever. Just what kind of pompous, uncompassionate scumbag would tell someone who genuinely wishes to end their life, someone who is at a point of such grave desperation that they see no other escape from the pain they experience every waking moment of their life, that acting on their desire makes them morally inferior to a rapist or a thief or a murderer? What a bunch of pretentious, unadulterated nonsense.
Why does it even matter what he tells them? The only reason you'd want to avoid being compared to a rapist or a thief or a murderer, is if you still cared for the things of this world.
