You can’t possibly compare things like driving to ending someone’s life.
generally if someone is killed in a car accident it is just that. An accident. And if not then criminal proceedings may follow.
Drink driving is in fact banned, so although alcohol isn’t, what we can do with it has pretty tight laws.
The difference between those and assisted suicide is that if someone feels obliged to end their life because of other people there is no way to guard against it. All they have to say is that it is their wish and the doctors will allow it.
As PP posted above, even if assisted dying is made legal the majority of people on this thread wouldn’t benefit from it in the circumstances they outlined, and that will lead to more campaigning. Let’s add dementia into the mix, then let’s add brain injuries where the person no longer has capacity and the family are left with the burden of looking after them.
Unless you make assisted dying limited to the terminally ill with less than six months to live who is of sound mind and able to take the medication themselves there is too much scope for abuse.
And the instant you start allowing for the mentally incapacities to be killed you are starting to enter into the realms of eugenics.
