This is a very difficult issue and frankly while I can accept that someone who is hopelessly ill might well want to end their life, there is to me a very great difference between that person him.- or herself being able to commit suicide, which in slightly old-fashioned terms is what we are talking about here, and assisted suicide, which morally and ethically is making someone else into a murderer.
We have to face the fact that euthenasia can potentially be misused by relatives or nursing staff talking someone into that option, or in the case of someone who is no longer able to express their wishes being used against the patient's own views.
Any law that contenances euthenasia has to take all these things into consideration.
As I do not live in the UK I cannot possibly know whether those of you who say that palliative care frequently is a matter of denying people food and drink, so they basically die of dehydration are correct ,or not. To me it sounds highly unlikely, as the risk for whoever actually made that decision or carried it out of being prosecuted is very high.
Personally, I have no desire to live in a state where euthanasia is legal. I feel we can and all should make our wishes regarding terminal care known to our family and our doctors upon receipt of a serious diagnosis, or in advance of any such thing.
The difficulty here is, that we may well think one thing while we are hale and hearty and the opposite if the day comes when we are dying slowly.
