Firstly my thoughts go out to his family. They have had to go through Hell watching him suffer.
I do not profess to know the answer to this one. With many years of experience as a nursing sister, I can understand the dilemma. What I cannot come to terms with in this debate is the assumption that all doctors out there would be willing to take a life. A doctor's responsibility is "do no harm". Of course, as in Tony's case, there was no treatment given to prolong his life so, Nature was allowed to take its course but, that is very different from actively killing the patient.
When the Abortion Act came in, there was a get-out clause allowing medical and nursing staff the option not to be involved in the care required. A recent court case went against that. Is this likely to happen again if a law was passed permitting euthanasia?
I do not envy the law-makers having to make a decision in this matter. I am only glad that I do not have to do so.
