Don't mean to pile on because I suspect by now you've realized how dumb that comment was.
If not, consider this: They were having a hard time controlling the plane. They were busy and rushed with an emergency return and it's more than likely their Jepp's were flying all over the cabin. Using all available resources is always the correct answer in an emergency. I sincerely hope if you're ever in a similar situation, you don't hesitate to ask for anything that lightens your workload. In the end, they got the plane down safely and no one was hurt. It's pretty hard (and petty) to second guess that outcome.
As for the the upset pax comment, I thought it was pretty damn funny. I'll bet he was right too!
