While the embryos all do indeed have the potential to one day live independent lives, one shouldn't deny the fact that at best MOST of them will die, and, possibly ALL of them might die. Many, many, many embryos die for one successful implantation. At least the friend represents an already independent life that will definitely live if you help him. There is no possible way to save a single embryo without being complicit in the murder of many more. This seems like an effort to push the problem of what to do with all these embryos back on pro-lifers. Sorry, but the vast majority of these embryos are doomed because of those who created them outside of the womb, not because of those who objected to this abuse of life from the beginning.

Its the parent's fault.

The only people who I see putting this argument forward are people who don't have children. You can't be with a kid (especially age 13+) 24 hours a day to monitor them, and even if you teach them well and they're respectful of your wishes and teaching "don't do this," by definition as human beings, they will do it. Thus, the laws of the state exist to protect the child in the void of their parents' oversight and teaching. It's not bad parenting, as you claim - it's reasonable.
