it is pretty vulgar betting beer on the cause of death of 7 people.
If we were making wagers before the event....I would agree with you to an extent.
How many times have you flown with someone and thought to yourself....."This guy is going to kill himself one day!"...knowing he might just have passengers with him when he does?
If you did think that and said nothing to anyone....especially the nimrod in question at the time....then I see that as doing just that...wagering on the manner of death of people in the future.
