It is in the interests of our society to promote those things that take the edge off, keep us busy with our fixes, and keep us slightly numbed out and zombie like. In this way our modern consumer society itself functions as an addict.
What people fear most about tragedy is its randomness - a taxi cab jumps the curb and hits a pedestrian, a gun misfires and kills a bystander. Better to have some rational cause and effect between incident and injury. And if cause and effect aren't possible, better that there at least be some reward for all the suffering.
