Untimely deaths are all equally sad. I don't consider a pedestrian killed by a drunk driver, or a person killed when their propane furnace explodes, or someone killed in a coal mine, or someone killed by a suicide bomb in Afghanistan any sadder than each other.
Some deaths are completely with no fault of their own (former two)...some are due to risky situations that the person is in (latter two). But they are all sad and unfortunate.
The only situation that is somewhat less sad are those who really get risky, like climbing up the side of a building without ropes. I consider that to be thinning the herd.
