Since you ask, I’ll try to make my point more clear. In the actual world, there are horrible diseases that can be (and commonly are) transmitted by a bite and result in death. Rabies is the archetype of this pattern. Get bitten by somebody who has rabies, you too will get rabies, and inevitably die of it. (Given variables of actual transmission, lack of treatment, blah, blah, blah……) That correlates nicely with “everyone who gets bitten by a zombie gets a fever and dies" as a true statement. As far as has been revealed to us, except for a single case involving speedy amputation.
And “everyone who dies becomes a zombie” is also true. Of course, one does not preclude the other. Both can be true statements. And, stated exactly the way you state them, indeed both are unassailable.
What you’ve left unsaid is that “everybody already harbors the zombie virus” (pathogen, germ, whatever). And this has been stated as a fact in Walking Dead World. So it too must be considered as true.
This poses the conundrum. If having the virus introduced into a healthy person by means of a bite gives you a fatal illness, then why don’t the people who already harbor this virus (“everybody” according to revealed wisdom) also just get sick and die? (And, once dead, then zombify and return.)
This, like a repeated water drop to my forehead, bothers me. Not enough to totally destroy the entertainment value of the series, mind you. And not so much as might perhaps be inferred by the frequency of my posts in this thread. After all, I don’t have anything else WD-related to occupy me until new episodes air.
But it bothers me enough to make me grouse at the writers for ignoring it. There are tons of easy, facile “explanations” that would remove the conflict. Maybe everyone hasn’t been exposed/infected after all. Or maybe there are two things happening, one that makes people die and a different one that makes the dead zombify. Or somehow a bite serves as a catalyst, without which the harbored infection remains dormant. Or…… Well, whatever. Then I could move past this petty annoyance!
(And take up the big questions, like Why doesn’t everybody roll in zombie goo before going “outside”?)
