Hi Cyrus,
I can empathize, but not totally agree. Sometimes death can no longer be avoided. Why not ease the pain? This is what hospice facilities/services are set up to do in the U.S. I assume there is something similar in Spain. The death doula apparently exists not to sooth the physical pain but to be a source of comfort, personal attention and compassion at a difficult time. I have no problem with this myself, though I think it could/should more ideally be provided by family and ministers.
However, having gone through the death of loved ones, I know the active young cannot always be there. Everyone has duties to children, spouses, bosses, clients, customers, other parishioners, etc. that have to be covered as well during what may be a long period of watching and waiting. And the time of death for a loved one--even when we know it is coming--cannot be set like an appointment to be kept on one's calendar with everything else set aside just so we can be there for the dying at that particular time. Family, friends, etc. will come and go. The Doula, IMO, is someone who can be there across this period just for the dying person. Ideally, family will also be present, but a Doula could also be there to fill any gaps in attention and care. A temporary role for a temporary situation.
Of course, there are also those without family or friends to hold their hand. A Doula then might serve as the last kind face or glance for the dying.
Cordially,
S&S
