Yeah, but I've known as many wounded children from so-called "intact" families as I have wounded children from single parent families, etc.

Raising children to become great adults isn't about how many parents you have, its about how you get treated by them, are raised by them, how available they are to you, how supportive of you as an individual they are (as opposed to being an extension of them, your siblings, their parents, etc). IMO, of course.
