You are shiftinf the topic. This is about self-euthanization, assisted suicide. Not others.
> Where do we draw the line?
As written elsewhere, having to draw a line does not mean that the only reasonable conclusion is to make it illegal in general. It's a hard topic without easy answers. "Don't allow it" is an easy answer that doesn't do justice to the topics complexity.
A good friend of mine passed away a year ago with an incurable disease, diagnosed 3 months before his death, and it was essentially guaranteed that he'd have to endure unbelievable suffering during the last weeks of those months. He didn't have the choice to end it early. It was heartbreaking.
I for my part hope that I can choose myself when the time has come.
When things get bad, it was usually not the drawing of lines that did it, but the intention and underlying stance on the rights and indeed humanity of others. The line is not what makes the slope slippery, but a pervasive lack of empathy seems to do it. We also know that bad actors do not care about lines much.
So I think that slippery slope is not a powerful argument on its own.
The politicians, yes. Auschwitz may return but it won't be voluntary.
That's a personal choice. Anyone not interested in that won't have to do anything and can just wait for the end.
“It shouldn't be that way” is not an excuse to torture people through your moralizing indifference to the fact that it is that way.
Currently? I'd say that I wouldn't want to live with dementia, but what if my "demented self" (kinda hate the phrasing, sorry) in the future wants to live, or doesn't remember they don't want to live?
Do I have a say over the life of someone who doesn't remember they were me?
It sounds like Daniel Kahneman was suffering from depression after his wife's death and all he saw in the rest of his life was sadness. He had no hope. What day was the best day to die? What if the next day his hope came back?
What if he tried that, but every day just got worse than the last day?
And people don't get any younger.
My grandmother is 98. She hates her life since she could not go out anymore. But she is catholic and suicide would be a mortal sin. So she waits till gods take her. And suffers till then.
I would make a different choice for sure. If life is hell and no one depends on me, why should I continue the suffering? (At the cost of others, if I would need help?)
But my plan is of course to reach 120+ in good health. But if I decide I had enough, it will be my decision.
I tell you this now in good faith, any human being can choose when to end it. That is without question. I can go get in my car and drive into the nearest body of water, if desired, and no law could stop me. Even under supervision 24/7, it is still possible to do it. We are a determined species.
The only thing in debate is if they can be ethically assisted in the task, with compassion. You say no, someone might pressure Nana into dying to pass her inheritance. Well, the same people might very well put a pillow over her face when no one is looking. A bad actor is a bad actor and murder is illegal but people do it anyways and moral hand-wringing doesn't exactly stop it from happening.
From where I stand you're just unknowingly advocating for extra pain and suffering. Perhaps you'd change your mind if you were in the shoes of someone losing their marbles or worse, someone who has to care for them.
