9/11 may be considered the worst, but I would say the CIA beheadings take the cake, especially when forced onto people
how would beheadings be worse than 9/11 anyways
9/11 caused 3,000 people to die, which doesn't sound that bad, but also caused millions if not billions or trillions of dollars in damage and a whole series of conflicts and instability that go to today
comparing that to someone losing their head is completely handicapped
