i think it has to be remembered that alot of these laws are also there to protect the weak, when you make this move across a certain line in the sand it starts to open doors to other things like assisted suicides etc.
there are people that want to end it becuase they feel like a burden on their family, they might actually want to live, there are others who's familys might see the financial advantage of "removing" a family member, even though they are wanting to live on.
others have been known to think one way when healthy, but when they find themselves in that situation they might feel different.
personally i can;t say i support suicide or abortion, i can see its place in society, but morally i don't think its right.
as with regards to myself, i do agree with ekonas original post where if i was left in a vegative state that i would be happy for the machine to be switched off. or to have a do not resusitate sign above the bed.
i think at the moment the fact that these issues have to be taken to courts of appeals etc is a good thing, it might be long winded but it makes sure the person going through this is serious about it and that the process doesn't become like a production line.
at the end of the day all life is precious
