This quote highlights the subjectivity of how much of a tragedy a death is. The dead do not suffer, because their consciousness is no more. However, the people that have closely known the dead usually do suffer, because our human brains are wired to do so. However, if an entire family dies, such that all of the people that would strongly mourn eachother are dead, then no one would suffer.
By the way, this community appears dead (no pun intended). Hopefully I can revive it.
