I've been reading and not posting but decided I should share my own story as others have done.
In most cases, EOL care is evidence of, not giving up on a loved one, but of absolute love for the loved one. Love is about being selfless.
My mum had a head injury where the healing process didn't stop and instead become a destructive process which ate away at her brain
Eventually we came to the conclusion that we should stop bullying her to eat (because that's what we were doing
) and allow her to go peacefully. She didn't want to eat and in the last few days of her life just had mouth care - gel/moisture swabs (that looked a bit like lollipops) as she could no longer swallow. The last thing I did for her (a few hours before she died) was to massage her hands and arms with a lovely lavender scented cream. I'm not sure how much she was aware - as by that point she'd also lost the ability to talk.
It's a horrible thing to watch the person you love disappear in front of you - but we feel no guilt for having made the decision to stop sustaining her, as all she was doing was existing (and in as much as she was aware, hating that - so that the one thing she could do, control if she wanted to eat, she chose to stop doing).
I still miss her, but she had gone a long time before she actually died. 
Picking up what derxa was staying, my dad (who loved my mum dearly) was a cattle-farmer who then trained to be a doctor. He was/is very matter of fact with regards to life and death. As an atheist, he hated it when people would say "She's in a better place now" or "She's at peace". He would retort (not usually to their face
but often to me later), "She's dead. That's the end of it". But we were happy that she was no longer suffering. It might help others to think that people have "moved on" when they've died, but not everyone.
On the positive side, my mum's well-documented brain (from scan following her accident to her death 5 years later) might help increase understanding of the proteins that were involved in destroying her brain and how they can switch it off (which might also help things like Alzheimer's and/or post concussion injuries)
just wish the research had been far enough along to save her
