Tragic? Shameful, anger-provoking, unfair, pitiful - but I wouldn't use the word tragic in this kind of context.

Also grotesque grand guignol stuff. Which gets classified as a sort of shock-humour. Very rarely actually funny, but the presumoption is that it has some kind of cathartic role.

If I was writing a song about this episode I wouldn't go directly down the funny or the tragic road. I'd be writing because I had something to say about the attitude to death in a society that didn't like to think too much about those things.
