Saying that something makes someone "mildly uncomfortable" and that's enough of an excuse for it to be illegal are being "so selfish."
That's essentially the basis of nearly all of our laws - the idea that death is "unacceptable" is the basis of nearly every law we have.
Drug laws, seatbelt laws, abortion controversy, etc. These things exist because we view death as "bad" - something to avoid. Society says that death is a sad, tragic, terrible thing. Nobody questions this ... nobody at all. The very mindset is selfish.
We don't want people to die because then we will be left without them. The people who are dead certainly don't protest, and can't. Their suffering is over. The people who are left suffer and take it out on the survivors in "memory" of the person who died or whatever random bs.
We all die - we all poof and go away. Why is it so culturally ingrained that life is valuable and should be preserved at all costs? Because most of us don't want to die? Sure - there's a real fear of the unknown, but then you could argue that most of us didn't want to be born either - it would be just as terrifying from the other side.
The truth is, we are comfortable with life and living because it is all we know, and we seek to preserve life for this simple fact. Limiting suffering makes sense, because suffering sucks and is bad ... but we destroy lives over the suffering that families feel over a loved one dying - and I mean that we send people to jail for drinking and driving and killing people; we put people to death for taking the life of someone else - thinking that our loved ones who have passed are looking down gleefully cheering as their killer is killed.
Does that seem rational or make any sense? It shouldn't. It's sick and ridiculous.
For all we know, being alive is the ultimate suffering. Nobody argues or questions any of this - it's unintuitive. Therefore, anything that isn't life (see: death), is horrible and bad.
It's like this UNTIL we decide that quality of life deteriorates to the point that it is mostly suffering. THEN, we turn back on everything we say and believe and feel that it is more humane to end that life.
It goes against everything we are taught and know our entire lives.
It raises questions like, how bad does life have to be for the individual until they are allowed to kill themselves? Certainly not something to be carried out on a whim, right? Only when a doctor tells you that you're going to die "soon" and that your condition will "worsen" and we can all agree there... or that your condition is "so bad" that it seems bad to us ...
It's all very gray and far more complicated than you make it in your tiny comment. In fact, the very idea that life is worth preserving etc. yadda yadda is questionable at best.
That being said, we certainly can't have the fear and chaos that goes along with wondering if someone will walk up to us and kill us today, although that's a very real threat every day we are alive.
My point is that you say it's "selfish" to find euthanasia unreasonable (see: choosing to allow someone to kill you) when nearly every law exists to make this impossible.
I don't care if everyone speeds - I say get rid of the speed limit or make it optional, but a million people will jump up to tell me how ridiculous and chaotic that would be. It's unacceptable for me to choose to allow someone else to kill me if that's what happens, because other people don't want that.
Does that make sense to you?
