Then there's the question of how that is legally managed. I pity the fool that is sued for stopping a suicide. We would often not know enough to make a 100% accurate determination. So, do we stop suicide in general and risk having living people who had the right to die, or allow all suicide and risk having dead people that didn't?
Or worse, your suicide casts suspicion of murder. You off yourself but your family doesn't think it's possible, they suspect your spouse and now you've got a murder investigation.
All roads point to suicide beings something that needs to be entered into carefully, somewhat publicly, and with the necessary checks in place. Of course that's
almost impossible given our culture of "suicide is bad mmmkay?". The thing about suicide is that it's an unpunishable crime (if you do it right). It's not like you're going to get arrested after you're dead... and throwing the book at someone who has just attempted suicide and failed seems like a poor way to speed along recovery.
But I think it might still be possible in the case of the elderly or terminally ill. If you honestly want to end your suffering, I think your family will go along with it - which would be the fastest way to establish that you don't have any outstanding debts or obligations. It wouldn't take much in the way of paperwork to establish that you're clear of obligations - to give your doctor the go-ahead to help out. Doing it at home, with a family member helping, is a fantastic way to cause a family fight and possibly murder accusations. Especially if the person helping is in the Will which... of course they are because they're close enough to assist with a suicide.
So I will not contest that it is a difficult thing to do right. You need signatures, agreement, doctors, possibly a financial check, etc. to do it right, to do it in a way that ensures that it's moral... to do it in a way that should be legal. But none of that precludes the right of an individual to end it all.
I haven't lost sight of the fact that the hypothetical that brought us down this road is a mother taking a
chance with her life during delivery rather than deciding to commit suicide. It's a little different.
