If you check any day's programming just on terrestrial TV, you'll see it's basically murders - from Murder She Wrote to CSI, the Bill, all those crime shows - and injuries (ER, Holby City, Casualty) etc. Throw in a smidgen of arson, terrorism and plagues breaking out, and you have the plot of a large amount of programming, and most mainstream Hollywood movies. Which means that nasty but interesting things happening to other people are the entertainment 99% of the population chooses to watch, in fact can't get enough of, for vicarious thrills. At least you are pitting your skills against those unfortunate illnesses and injuries and actually helping people - and if you weren't hungry to do your job, you'd be rubbish at it. I knew someone who was murdered, and in real life it's not remotely entertaining or glamourous, it's just sad and ugly and horrible, but I admit I'll watch the occasional CSI like everyone else....
