I am glad he met his end. He was a terrorist and a mass murderer as well as a coward. Osama ordered others to do his work as he remained thousands of miles away in safety.
That said, let us all remember that as bad as he was, he had family that will grieve over his death. He was a human and in death, his remains should be treated with respect. Whatever he did or did not do in his earthly life will be answered to by his maker and his fate has been sealed. Too often I have seen people kicking the bodies of deceased persons, spitting on the bodies or whatever. Treating Osama's body in any way other than respect would only anger others in his religion. They may not agree with what he did in life but by religious teaching and tradition would want his body to be respected.
I would have rather he were captured and spend yrs in a small cell and then be executed by court order. It would have given him a long time to think of his actions and his fate.
