I have a male cousin who has been an addict his entire adult life. Just out of highschool he got together with a female addict and together they produced 6 children within a decade. They could not raise a single one of them. They pawned them off within the first 6 mos of their lives to grandparents, parents, aunts...etc. One 86 year old great-grandma was raising a 2 year old. All of those 6 children are in their 20's now. 5 are hell-raising. 3 of the 5 hellraisers have multiple children being raised by relatives. But 1 of those 6 worked hard, went to harvard on scholarship, became an MD and opened a clinic where she treats children of drug addicts. So which kid do you stop from entering the world?
