How ironic it would be if the slide toward the culture of death resulted in your demise before you wanted it, because someone else had decided against your view that you were not enjoying a sufficient quality of life.
What strikes me in the quality of life argument is the notion that whatever human experience comes out of a lesser situation will be, of necessity, inferior to that which comes out of a better endowed one.
History, as well as my personal experience has taught me not to expect the best from those most priveleged, but rather from those who have faced the most adversity and overcome.
On a personal note, as the father of two adopted children, I thank God daily for their lives, despite the fact that they have not been always the easiest of times. For someone to suggest that they (or I) might have been better off if I or their birthmothers had sought a better "quality of life" for ourselves is anathema.
