Which is probably why religion was developed in the first place, for its comforting effects, as a balm, a bravery-enhancer, a coping strategy for dealing with inevitable death.

I think the way we deal with death nowadays has more to do with arrogance or hubris, coupled with wishful thinking. We're used to thinking we control things, and can get anything we want. One thing useful from the religions was having a healthy sense of your own limitations, or you could say a sense of wonder or mystery or perspective. A reminder that you're not the most powerful thing in the universe. Which is true, and healthy to be aware of, whether any god exists or not.

Edit to add: There are few places where that hubris and certainty tend to be more pronounced than among doctors. Part of what this woman is grieving is probably the loss of certainty, of control or the illusion thereof.

It maybe a factor, but I do not think it was the main one. Death is still very hard to cope with, regardless of religious belief. There are other things behind religious belief, mostly experiences.
