It's kinda like how the Egyptian gods operate. The Oracle is not mortal. It is a spirit that can pass from one mortal to another. You can probably kill the human host but not the Oracle itself. Hades had the power to kill the Oracle's last host but the reporcussions would've been horrible. If the Oracle's host is killed or dies before the spirit is passed on it will probably find a new host.
