I want to write a long post on this but I'm somewhat short on time so I'll see how this goes.
OK what I've actually done is just drawn up a list of questions that need answering. I'll return to answer my own questions later on.
Considering that pain is subjective, is someone with less tolerance a better candidate for AS?
I don't believe we can use the term 'better candidate' as this whole issue
is subjective. One person may be content, or able to live with being paralysed from the neck down, or having terminal, painful breast cancer. Another may want to die soon, with their own terms and conditions, painlessly and quickly.
Does the considerable amount of pain medication available negate the pain argument?
Not in the slightest. Despite their being a considerable amount of pain medication available, not all medication works for all conditions. Also, many pain medications that could work may 'knock out' the person, so they sleep all the time, or make them so 'high' they can't function properly or have any type of life quality. Different medications work differently for different people, and for some the options of lots of pain, or being so knocked out they can't live anyway means they may want a third option - suicide.
In situations where there is no physical pain (paralysis) is emotional pain a sufficent reason?
Definitely. If I were paralysed completely, or like a 'vegetable', I would never want to live that way. Having to live for the next 60 years unable to move would be unbearable to me, and I think those who feel the same shouldn't have to find a way to fly to Switzerland to die peacefully.
Is terminal depression intolerable enough to justify AS?
I think the issue to me for assisted suicide is that depression isn't generally something that physically stops you committing an act if you really want. Someone with terminal depression could kill themselves, with no help from anyone else. I'd use assisted suicide as a way to help those who can't physically kill themselves, but are mentally fine, and have made their choice. Depression would need to be looked at in detail, from experienced qualified people as to whether assisted suicide would be allowed in those circumstances - as of now I don't have a strong opinion either way.
Is someone "suffering" in the right state of mind to be able to make a subjective and unbalanced decision?
Suffering doesn't equate to not having mental capacity, and every adult has to be deemed to have mental capacity unless proven otherwise. If that is proven, their decision can be questioned. However, just because someone is in pain, and wanting to make a decision you deem as unwise, it doesn't mean they aren't capable of making a decision.
Also, I'm not suffering any physical or emotional pain at the minute - and yet I say I'm almost completely sure I'd want to die when faced with situations of paralysis or a complete lack of dignity permanently. I say almost completely now as you can't ever know for sure until you're in the situation, but I'd say I have a pretty good idea that being in the situation would eventually lead to me wanting a painless, fast death for myself, when I choose.
Where is the line drawn in terms of life quality?
Completely based on how the patient with the illness feels. As I said above, there are some situations one person could live with and another would want to die with. Each situation would have to be looked at individually. Remember assisted suicide isn't about having a list of illnesses we kill people with, but how every individual feels with their symptoms and circumstances.
Is paralysis a terminal illness or just a severe injury?
It depends how you define a terminal illness. I've always thought of it as an illness which will go on to kill you. Paralysis doesn't necessarily do that. However I don't think that means assisted suicide shouldn't be allowed in that situation.
Giving the progression of medical science, is it ethical to end the life of someone who may recover?
I think this is solely a question for the person wanting death. Some may be able to wait with that hope - others not so much.
Whose decision is it to make and can someone suffering ever make a objective and unbiased decision
It's the decision of the person wanting to die, ultimately. They need to be assessed with medical experts to ensure this is something they truly want and that they understand the impact of.
However, the issue becomes more complicated when the person is a 'vegetable', for want of a better term. Someone with little brain function, no way of communicating, unable to move..but technically alive. How do we determine that particular decision? Because it should never be something a medical expert decides. And yet if it were me in the situation I'd want my mum or husband to decide to let me die. But that just brings up a whole host of new questions. How do you decide who genuinely is acting in the persons best interests? And how do we know they aren't doing that due to a benefit they'll get, such as money in a Will?
In circumstances where you had the chance to kill yourself and chose not to, is it fair to then ask someone else to do what you failed to?
I think it depends on circumstances - have they changed a lot since not committing suicide and suddenly feeling you need to? But I'd be wary. If someone couldn't kill themselves yet is asking someone else to do it, I'd likely think they didn't seriously want to die. Or maybe were looking for attention as opposed to death.
Does assisted suicide go against the very essence of a doctors hypocratic oath?
One of the most difficult questions here. I personally think of the Hippocratic Oath as something which means all doctors should work to prevent suffering in their patients. Others think of it as preventing death, no matter what the cost or implication. I think this would have the same type of argument as abortion does amongst doctors. Some won't perform them, others would in certain circumstances.
Would legalization and ethical acceptance lead to the public taking matters into their own hands
The public already take matters into their own hands. Asissted suicide is legal in places like Switzerland, and as yet I haven't seen anything to suggest there's been a negative impact on society, although I haven't looked very hard for anything so that would need to be looked at.
what legal standard do you apply though? Verbal? People lie, or often say a lot of things they don't really mean. Do they only have to tell it to you for it to be legal? Does it have to be written down on a signed document? Documents can be forged. How do you prevent people with ulterior motives from staging an "assisted suicide", making it look legit, because they had something to gain from that person's death? If you allow people to help other people die in an active/participatory role, it is VERY easy to blur the lines, and even if you distinguish a difference between murder and assisted suicide (I don't) there would be plenty of people getting away with murder under that guise..
Everything you've said is what happens now. By legalising assisted suicides there would be a correct method. A legal method with witnesses, psychiatric reports, qualified doctors, specialised centres. Those not following that strict code could very well be found guilty of a crime.
