I think the blood eagle would be a pretty horrifying way to die.
If thats not a horrible way to go I don't know what is.
"The Blood Eagle was a method of torture and execution that is sometimes mentioned in Norse saga literature. It was performed by cutting the ribs of the victim by the spine, breaking the ribs so they resembled blood-stained wings, and pulling the lungs out. Salt was sprinkled in the wounds. "
