Like i said before i sit on the fence, its so difficult to say whats right and wrong.
But like Blah11 said there are so many diseases that are terminal, its not just cancer, but cancer patients often get much better care than people dying of say motor nuerons or dementia. Palative care for cancer pateints includes basically overdosing or morhpine near the end, its theaputic in the sense that it takes the pain away, but it will kill the patient, my grandad recently died of lung cancer and he received this treatment, at home, apparenelty once they decide to do it that pateint dies within 3 days, although he last a lot longer but everyone was surprised by that.
Dementia patients dont get this sort of palative care.
Children is difficult isnt it, i would say its the parents choice, but then my sisters keeper is one of many examples where children say they have had enough. although in those cases its less to do with euthansia and more to do with stopping treatment. I havent heard of any cases of euthansia clinic's with children, but i have heard of patients drowning or intentionally overdosing there children, i hope im never in the position to see my child suffer everyday and beg me to end it, i have no idea what i would do. I dont think its right really, but again if i was in that position and seeing my child suffer and know things would get worse i have no idea. I cant imagine how any mother could kill her child, but i cant imagine the pain of watching a child suffer either. I hope i never ever experience that.
