Oh I don't know... "I'm in such terrible pain and Keith makes me do all those evil deeds that I'm afraid I'll never be able to meet your mother in the afterlife. Please release me from this living hell!" would surely have gone a long way to make Gray kill him and as an added bonus it would have eliminated the risk of Gray comitting semi-suicide via Iced Shell.

And if that didn't work, he could still have fallen back to pretending to be Deliora by saying: "Hahaha that was really funny. I just love to see you suffer. Oh just so you know I'm really Deliora and now that you suffered enough to satisfy me, I'm going to kill you and everyone you ever cared for."
