I am also conflicted.
I really do not want to see anyone suffer, but how often do you hear elderly women say " I don't want to be a bother...." do not want to bother the doctor, feel overlooked lonely and ignored, have decisions made for them due to lack of confidences? We hear of homes sold over the heads of the elderly and children taking control of money. Something of a short step to "time to go". Depression and internet encouragement is already a major cause of suicide.
It makes me think to abortion legislation. We introduced this on the back of women dying because they could not medically undergo childbirth, of children being raped - yes, it was going to be the exception when medical needs must. Now it is a standard means of contraception, and girls can be less reticent sexually and men can be lazier because there is always the morning after pill or an abortion to be had on demand.
The case for assisted dying, like it was for abortion, is based on the worst and needy cases, but how long before it becomes a standard way of easing the nuisance, lingering, needy elderly and infirm out of existence? Or simply those who cannot afford care?
Then how long before we drift into the Nazi mindset? It was not just Jewish people, it was the elderly, the mentally impaired, the congenitally different who were sent too.
Nobody suffers in pain (a morphine dose is increased to cope, right up to the point where it can hinder breathing already), and technology helps the weakened ( Stephen Hawking comes to mind), gene therapy advances daily too.
