And that's the problem; people are too quick on the draw. Why are they so eager to kill people? Don't they realize it could be THEM next time?
It usually boils down to money. The common case is saving the cost of care, especially the heavy costs typical for people near the end of their lives. Former Colorado Governor Richard Lamm stated the matter plainly, saying that seniors have a DUTY to die. This kind of thinking infects all socialized medicine because in those systems, care must be rationed. It looks as if the elderly are hogging the care.
However, things don't work that way in private medical markets, which allocate resources differently.
Money plays a huge role in organ transplant cases (which is what I suspect was afoot in Haleigh's case). Here you not only escape the cost of care, you may make a six-figure profit selling the organs. The only trick is, you have to declare the patient brain-dead (a new definition of death invented at Harvard in the 1960s in order to make organs more accessible for transplantation).
Cases where money is not involved at all? Well, there are always a few sociopaths like Ted Bundy, Jack Kevorkian and George Felos, who kill for thrills or for the fun of it.
1. Organ donations. There is enormous pressure coming from doctors, hospitals, and other interest groups who stand to gain prestige and $$$ in the hugely profitable body part transplant industry.
2. A debased culture that no longer values life. Scratch a euthanasiast and you will find a "pro-choicer" underneath.
They are eager because of $ - health care $. Thank the expense of taking care of illegals for that problem, in part.
