I would never have the patience to raise my own child. Period. Anyone can tell me that I would when the time came, but I KNOW MYSELF. It would never happen. I think yes, to some degree, children have little sense of right and wrong, but they learn very quickly what they should and should not do. Why do kids cry? They know it will annoy you into coming and paying attention to them. That's not being mean, it's just fact. Children are eleventeen brazilion times more aware of things than anybody gives them credit for. They quietly observe the dynamics of what goes on around them and they pick up on how to manipulate adults. Problem is, most of the time, the adults never even realize it, until bad habits have become solidified as part of the child's way of dealing with things.
EDIT: Yes, I know they cry for plenty of legitimate reasons also.
