Death of Osama bin laden

I mean I do think that he was a horrible person that was the cause of many peoples death And he did a lot of bad things including being a big part of 9/11. But to me Even though he did all that stuff and has had America scared sense 9/11 but I think its wrong to celebrate someones death I mean I do know that the "experts" say it was his DNA and it was him did we really see the body? Its not like this is gonna change anything 9/11 still happened and him dieing may be a little bit of relief but who know this might just be the beginning.
