That I consider this a bad episode. Powerful and difficult stuff, right up there with the best of Star Trek.
Not sure that I agree with the comments that it makes the religious people look crazy - as far as they were concerned the spirit was damaged, and who are we to know it wasn't? That's the point of it.
I was against Franklin interfering (maybe it's after so much Trek and non-interference, or maybe I just think the non-interference thing was right) and felt that it simply proved that the only difference in the end was that he gave the kid false hope and caused distress to his parents. Even if he'd lived, what kind of life would he have led on the run from his own people?
But then, well, he'd have had more of a chance than being dead.
Who knows, it's not a black and white answer, it's extremely difficult. And that's what makes it brilliant.
