They were fools who were so arrogant as to think that saving a few lives would have meant anything. I think someone needs to tell that to the family members. The world would not have ended if 5000 people as opposed to 3000 died that day. America would still be a country. Only a few weak minded family members would mourn.
And they certainly crashed the plane for nothing. Will they get special rewards in heaven. Unlikely. At least the hijackers did it for something they believed in. Defeating what they called the ‘Great Satan’
