All of the pirates that took a piece of gold out of the chest have to repay the blood. In Aztec mythology, the gods were big on human sacrifices, and offerings of blood. Since it was Aztec gold, giving the blood back is a ritual to appease the gods, and lift the curse. Since the pirates admitted to sinking Will's father, they need the next closest thing to his blood, which would be his direct descendant, his only son, Will.
You have to listen to barbosa's speech when elisabeth is hanging over the chest... he's telling that everyone of them "paid their blood sacrifice more than once. and who's blood must jet be spilled?!"And then they point at Keira, thinking she's the daughter of bootstrap bill.
So the point is everybody but bootstrap already paid back the gods with their blood.
Interesting: Will's father took a piece of the gold, sent it to Will, and then the crew of 'The Pearl' sunk him to the bottom of the ocean. If he took some gold, he was cursed and couldn't actually die when he sunk. So in essence, when Will lifted the curse, he inadvertently killed his own father, who was on the bottom of the ocean, cursed, and unable to die. But once the curse was lifted, he would have drowned!
How was the father of young Will (Orlando) called in English??
Will.... Turner.
Damn, they translated it here
Bootstrap Bill Turner... that's why they tied him by the bootstraps when they fired him off to mars

He escaped on the back of a couple of sea-turtles lashed together with human hair, silly!
Don't forget it was from his back!
What I don't understand is... what's wrong with just letting the pirates be freed from the curse? Give the poor guys a break.... far out
