i thought the whole point was to use the child for an emotional response? Nurti (it was Nurti right?) KNEW that the Tau'ri would NEVER leave a small child alone on a planet, no matter what was going on - sick, dying, etc. - the Tau'ri would do one of two things - stay with the child until she died, or take her back to Earth to try to heal her, or care for her - and guess what? Nurti was right - that's exactly what the Tau'ri did - that was the point of the episode - to show the compassion that humans feel for others - to show that the Tau'ri are different from the goa'uld -
(now, there might be other similar qualities btwn the Tau'ri and the goa'uld, but that's another topic)
