Depends how he said it.
If he expressed the view that the US/allies action might be counterproductive, then fair enough. If that's all he was doing, seems unlikely this action would have been taken.
On the other hand, if he was being sympathetic to Bin Laden, he deserves what he got and what he gets.
I for one wouldn't want to share a flight deck with him. The risks are too great at the moment to take chances.
