Celebration of death

        So, as most of you already The death of Osama Bin Laden was confirmed by president Obama on May 1st 2011. And upon the release of this news, many places I go to online (*cough* Facebook *cough*) has exploded in expressions of celebration, skepticism and debate. However, one of the biggest arguments I encountered was the debate over whether or not one should feel happy about the murder. People are celebrating  the death, saying 'good riddance' and 'thank God,' while others are claiming that it was a bad thing that he was murdered. Often they say that his death was not worth the amount of lives needed to kill him.
      However, I notice that there is a flaw in the logic of the objectors. What they claim is that his death was not worth the cost. While the celebrators are just celebrating the fact that a dangerous enemy that killed many people is gone. The objectors and celebrators are discussing two completely different things. I am sure that most of the celebrators would agree that the life cost was too high in order to finally get him, but that is not the point. The point is that he is out of the way finally and can do no more direct damage (however he might inspire a couple terrorists who make him out to be a martyr).If the objectors truly wished to argue this case, then they would need to argue more along the lines of how murder and death is always wrong no matter what, but I am sure defending a terrorist who killed thousands of people and promoted hatred and violence won't go over very well.
     Is it alright to celebrate the death of an enemy?
