As we are all religious - and aethism IS a religion - i feel the following points need to be brought out in this debate.
1. If a person feels THEIR existence is cruel and far too painful to go on then their wishes should be respected WITHOUT laying their nearest and dearest open to crimal charges for assisting their death.
2. As we all know PRESSURE will be put on some people to die by their supposed family or indeed by a supposed caring government.
3. Medics must be protected from having to agree to implement this law. Most become doctors to save life and under no circumstances should that precept be violated. NEITHER should a medical job offer OR terms and conditions be dependent on agreeing to implement assisted death
So long as point 1 can be met and points 2 and 3 defended against, then I can't see the problem myself in allowing assisted death.
But as we all know 2 needs a bullet proof legal process in place and we all know how difficult that is.
Point 3 also doesn't tend to work in the long term (see retail work on Sundays as an example) - it can't be modified in any future variation to the legislation or the hiprocratic oath they all took could be violated END OF. Individual doctors may thing that avoiding cruelty is part of the oath - most do not and feel life is a inviolate part of the oath. It won't become a local NHS service and that's for sure - not if you want an NHS anyway.
Point 2 means relatives of an individual, or indeed the government cannot decide what should happen. Only a living will can provide sufficient safeguards against unscrupulous relatives - I'm afraid "Power of attorney for health" doesn't cut it as the rules need to be set in stone.
