What would drive these people to do it?

I've often heard about september 11th, about how the U.S. would never really recover, but every time I hear that, I wonder, why did those people in the plane do that, what motivated them to sacrifice there lives to kill many others? There is the customary answer "they where crazy terroists", but I think there is something else. They didn't drop bombs, they dropped themselves, when people are willing to kill themselves to make …

…ever know, because they are dead. They killed innocent people, but we, in Iraq, are killing innocent people to, and we don't consider ourselves crazy. I think it is part of human nature to take action without really thinking, look at the greeks, they started an entire war over 1 women. I think that everyone is radical to a point, and that we need to think about these things before we make statements on past events.
