Like many others posting here I have had the misfortune to watch a loved one die, and seen the effect it has had on the family members around me.
My Grandad passed away from a cancer in the stomach which spread rapidly throughout his body. In the space of 3-4 months he was reduced from a fit and healthy, active person, to a skeletal wreck in constant pain, unable to move, let alone look after himself in any way shape or form.
Watching him die in this way also had a massive effect on my Nan, my Mother, Aunt, Sister, Cousin's and myself. All of whom are now firmly for assisted suicide, as we all knew my Grandads feelings towards it - if he had had the choice, he would never have chosen all the procedures he was put through which effectively ruined any chance of a normal end to his life, despite them having little to no chance of success. My Mum now has a "living will", to say that if she ever has an illness that reduces her quality of life, she would want us to take her wherever assisted suicide is available so that she is not a burden to those around her, and they wouldn't have to go through what we did with my Grandad again.
Assisted suicide in my opinion should be a basic human right. I genuinely do not understand why anyone would be against it.
