No Stupid Questions

Canada has m.a.i.d.

keeping sick people alive is a lot of profit.

Easy. Religious people who think humans are superior to any other life. This leads to killing animals for both merciful and vicious reasons. It also leads to keeping people alive by any Frankensteinian method possible while denying any death because "going to God" without enough suffering first isn't religious enough. Although big corporations also get the right to kill people (gun manufacturers, oil & gas industry, Sackler family, etc.) so long as they profit enough off the deaths.

Do you have any idea how much money there is in end of life care, nursing homes, and hospice? Its a many billion dollar industry. It exists mostly to rob estates from the elderly so the kids inherit nothing. Its a truly evil thing to prolong someones suffering in order to pad your bank account.

The US just pretends to be against it due to puritanical traditions. In reality we keep guns legal so people can blow their own brains out when they get fucked by late stage capitalism. Suicide is the majority vs murder when it comes to gun deaths.

Canada has Medical Assistance In Dying (MAID). People can - with medical approval and assistance - choose to go out on their own terms.

I wish we could do for our human loved ones the same as we can do for our pets.

You have noticed that there is a difference between humans and pets, haven't you?

Because while euthanasia is generally a good thing, there are also big potentials for abuse and unnecessary tragedy. We maintain a pretense of caring about these things with humans and so most governments err on the side of caution while others think they're such hot shit they can dance their way through the quagmire. Meanwhile, we openly don't give a single fuck what happens to non-human animals, and our culture is predicated on treating them like objects, so you're allowed to do whatever you want with them. Kill them because they're suffering, kill them because they bark too loud, it's all the same. It's your dog-shaped object, go nuts.

We live in a hierarchy of sentience. Where an animals' lives have less value then a humans.

Because pets aren't leaving anyone large sums of cash in their will.

Because most of the members of the society (people) belive that people have souls and animals don't.

because of WW2 and the experiences made there.

if euthanasia was legal, it would be immediately used against some kind of disadvantaged group, which is why it's kept forbidden.

It is actually legal in Canada, you have the right to kill yourself there

Much of it comes from Christian theology.

Suicide has long been considered one of, if not the, worst possible sins in Christianity. At least in the Catholic tradition, sins can be forgiven by confessing your sins to a priest and having them absolved. But you can't do this with suicide. Per Christian theology, even a murderer or child molester can some day repent, beg forgiveness, and be forgiven of their sins. They won't be absolved from the earthly consequences of their actions, but they'll be forgiven in the next life. That is a core message of Christianity - no actions are truly irredeemable as long as you still draw breath.

But with suicide, this isn't possible. You can't confess your sins after you're dead, and suicide means that your last act on Earth will be a mortal sin. I suppose you could maybe do confession along with assisted suicide. Maybe you have a priest on hand, swallow the poison, and then immediately confess your sin. But most religious scholars would likely argue that doesn't work. Your contrition has to be genuine for it to count.

Anyway, pardon the digression. But this really is the root of it. Even in modern Western societies. Even among people who aren't themselves active Christians. Even among those who've never stepped inside a church. Secular Western society is still heavily influenced by Christian philosophy. A strong aversion to suicide in any form is a part of this. For most Christians, voluntarily signing up for euthanasia is the easiest direct path to eternal damnation that one can achieve. The only quicker more direct way would be a murder-suicide. We've never had that same worry with animals. Christian theology doesn't assign souls to animals. And even if it did, they would have no moral blame for us choosing to put them down.
