Now we have an interesting conversation.
Hummm...
It can be considered very muddy if there were people awaiting for that blood to survive.
Let's say she really needs the blood to survive and there and a person with a normal lifespan that also needs it. You only have so much for one, and you don't know anything about any of them except how much they lived.
I would give the blood to the younger person. Eliza already lived dozens of lifetimes.
Of course, asking someone to die is too much. To forfeit continued existence in favor of someone younger is undoubetly a good act.
For a moment, I thought her story could go that way, but that theme was already covered in Squigly's story.
Also, the fake blood drive rubs me off very wrongly. Living in a corrupt country where the politicians robbed even donations for flood victims, it grinds my gears. It is a much easier act of murder, because you don't see the victims.
Human compassion has this bad loopholes.
