Most people can't relate to the concept of immortality. This is somewhat touched upon in HW where the life of a mortal is compared to that of a fresh cut flower. It's more like saying, you can bring back everything you ever loved but you'll have to destroy 13 colonies of fruit flies to make it happen. The average human being would have no problem with that as 1) they don't consider anything but humans to have value and 2) they couldn't care less about creatures with a 2-week lifespan.
