It's not a child. Even if you want to use a broad definition of child (and I do), this cell was not implanted in a women, and could not grow.
It's one thing to take positive action to stop a child from living (abortion).
It's quite another to simply do nothing. This type of stem cell research is done from cells that would otherwise be thrown out - you have not prevented a child from living.
It's really not what? Not a positive action that kills a child?
You have to see a difference between not saving someones life, even though you can, and actually going and killing them.

We are getting offtopic here, but sure you can. We make people take care of their children all the time. If they don't they go to jail for neglect or abuse.
