For me, death and dying of a loved one is not some esoteric issue, but something I have faced, and something I have faced as an heir, and expect to face one day myself, unless I am just hit by a truck one day and never face the onset of dwindling disease. Believe me, I know the costs, law, and most important, loss and grief involved when someone is incapacitated and dying.
It is presumptuous and rude for you to assume families cannot and do not make decisions about what treatment will work, and what treatments have no hope for benefit, and what is the best way to provide care that makes sense when it comes to their own family members.

It's far more presumptuous and rude to kill your mother because you can't stand watching her suffer--or spend all that money you're going to inherit on something as pointless as long term healthcare.
