I am not going to deviate for one woman who has every right to die if she wants. It is none of my business how.
You were wrong on all three counts.
Life is an unalienable right, which means that even the right-holder cannot abrogate it. One or others may afflict it, or abridge it, but it can never be abrogated. Hence there is no right to die.
There is no evidence that she wants to end her life. It is all hearsay from her husband.
The unalienable right to life is everyone's business. To allow the abrogation of her right to life would also inflict upon the right to pursue happiness to other sane people with normal human feelings who become saddened by the prospect.
