Not sure if it's possible, so forget about the omni-everythings and religion for a moment and ponder this.... If you knew some godlike entity was about to destroy you, your family or friends would you kill it in self defence if you had the chance, or kill it after the fact as a result of a trial or for revenge if there was a way? Do we have the right to kill a God if we knew that the god was about to do us in? Does eye for an eye apply?
