You should reread Paul, "O' Death, where is thy sting?".
I believe completely in what Paul is saying, and I have no fear of dying.
But I still don't find death funny, ESPECIALLY when if comes to people blowing themselves up in acts of terrorism.
Paul is talking about saved people. These people are the lost and their deaths are a tragedy no matter how you look at it.
The Bible says God takes no pleasure in the death of the wicked.
And I don't think it's appropriate for us to be laughing about it.
