You'd think they'd be pro-death and look forward to meeting them again in whatever afterlife they believe in. Or does faith falter in the face of the fragility of life?
There's a correlation between being religious and being "pro-life". Even the dimmest pro-lifer can see that it's hypocritical to insist on saving the life of a foetus that has never seen daylight, at the risk of the mother, while allowing an old, sick person to die naturally. So they are forced into an "all lives matter" posture.
