To live or die should be MY choice.

A 93yr old friend is dying a horrible and painful death. It was the end of November when it became clear that he was approaching the end but he still was mentally sharp and neither he nor his family wished for anything more than events taking their course. Those wishes were respected. He did not have to risk friends, family, carers, being prosecuted and having to jump through an array of 'safeguard' hoops in order to receive the care he needs. He has so far voluntarily succumbed to just over two months of constant pain despite the wonderful efforts of his hospice. For myself in a similar situation I have no doubt at all that I would have wished euthanasia as soon as it became clear there was no hope. My question is very simple. Who gives the Law & the opponents of euthanasia the right to deny me the respect for my wishes that is automatically given to my friend? We are constantly told that the issues surrounding changing the law to allow my wishes to be respected are 'complex'. They are not complex at all. There is not a shred of evidence to suggest that the opportunity that I seek would lead to slippery slopes and rapacious relatives getting rid of the tiresome elderly and all the rest of the completely spurious arguments presented by the 'all life is sacred' brigade [not so sacred of course when you send young people off to wars].
