Your comparison is understood and valid— you have a point. But it really is an extreme comparison.
On a more practical, “real world” level, I submit the examples of my parents who both died at young ages after long and horrendous battles with cancer. My mom never expressed a desire to end her suffering early to me— but I was only 16 years old at the time.
My dad, however, did express the desire. He said many times that he should just shoot himself, but he was worried about a number of things: that it would be physically messy and disgusting, that it would traumatize everyone around him, that he would look weak, and that it would have to be done secretly and that people would be angry, etc.
He never said “wouldn’t it be nice if there was an accepted form of suicide... blah, blah, blah...” but I am making that logical leap.
He was in terrible physical and psychic pain for many many months. IF there was a painless and generally accepted practice for ending one’s suffering, he would certainly have considered it.
And, by the way, he was a Catholic.
So, this is where I am personally coming from on this issue.
Oh, and one other thing. As said above, he was a believing Catholic, and I am a non-believer (at least for now). And when he expressed his desire to end his own suffering, I NEVER counseled him to seek it.
AT ALL.
I left that decision to himself. I never gave an opinion one way or the other, I just listened and held his hand.
I am not the “Cult of Death” that so many here talk about, and I submit to you that there are many other non-religious (and even religious) folks who behave the same as I.
There is. It's called palliative care.
