Of course this horrible woman is being outrageous in order to continue raising her profile. I suppose what we should do is just ignore her, but traces of these sorts of views are trickling into the mainstream (people, not necessarily just elderly people, being described as "a burden" - and even describing themselves in that way).
Given that KH is still a relatively young woman, I wonder if she will be quite so willing, when she is older and perhaps declining in health, to write herself off in this way. And if she really wants to bring her children up to be so lacking in compassion and selfish, I pity them and anyone whose paths they cross.
Someone with signifcantly declining mental faculties would not have the capacity to agree to "assisted suicide" - I think the term for despatching people without their informed consent is "euthanasia".
