I remember once putting in a Trade for ValueJet (one of their planes exploded and they were most likely liable). I put in a buy thinking the stock was too badly hit. But I still felt bad making a trading decision so clearly linked to human tragedy. The weird thing is that the trade just disappeared. I called the broker, they had no record of it--and it was a market order. I didn't complain about it at the time (and it prove to be a dog). But I just stopped trading for awhile. I just felt kind of ill. Just thought I'd share; I know it's not at all comparable to what you went through.
