Is it really right to be celebrating Bin Laden's death?

Everyone who has mentioned it has mentioned how happy they are that he's gone. Don't get me wrong, he was a horrible person who used his power for evil and committed unspeakable atrocities...but is it really right to be celebrating the death of a human being like this? He was a terrible, merciless human being whose death I do not consider a loss to this world in any way, but it feels wrong that people are celebrating his demise...
