Unfortunately the death of Osama bin Laden made him a martyr in the eyes of his followers.
The actions of martyrs tend to be copied by over 9000 of their followers.
Ergo, the West is screwed thanks to the death of bin Laden.
Even though it's undeniable that Osama bin Laden was a horrible human being, he shouldn't have been killed. His punishment should have happened through international trials and should've been punished according to international laws instead of having his flat raided and his "ass capped". That would've truly shown his followers that terrorism isn't tolerated at all. Having his ass capped means that the West is willing to resort to terrorism to counter terrorism, meaning that the original victims of terrorism will become the terrorists, and there's no way for the bloodshed to end.
In other words, oh bugger.
