Very noble. I still won't kill you for it, Mr. Stilinski. Especially not when it's something like cancer - if his body rejects the bite, he won't be healed. My resurrection... it's not perfect. The one person I saved truly still has to take a potion on a regular basis, to maintain herself. I had to heal her of her stabbing wound separately.
You could die and there would still be no guarantee that your father would live.
