No chance. People have always joked about death and tragedies. I have no idea why. Is it a kind of coping mechanism, tinged with relief it wasn't them or their relatives that died? Or are they just sick wankers, trying to be top dog with the sickest reaction? I'd say a mixture of both.
When the Herald of free Enterprise capsized off the coast of Zeebrugge in 1987 with the loss of 193 lives I experienced this first hand. In a matter of weeks I went from waiting for a ship for eight months to being employed by the same shipping company. They say one person's misfortune is another person's gain and so it proved for myself and many other unemployed seaman. The company had to replace the workers that had died on the Herald.
I digress slightly but just weeks after the tragedy I was onboard a sister ship of the doomed vessel working. If I had a pound for every fucker that laughed and said to me, "I hope they've shut the doors" in the first few months I could have retired a rich man. I was working with survivors of the Herald and everybody knew somebody who had died on that ship. Even I did. Geoff Haney from Wythenshawe, a staunch Blue like us,died onboard on that awful night. Needless to say this "Joke" went down very badly. Insensitive doesn't cut it but these cretins thought it absolutely hilarious to say it. My response was always, "You better hope they have or you'll be dying just the same as me and like the poor sods who died on the Herald won't you!" Some looked sheepish or snapped, "It's only a joke" I then told them everybody working onboard knew somebody who'd died on there so we didn't find it funny. A tough time. That's life though sadly, people make light of death and disasters.
