Zombie media would be a lot more suspenseful if zombification is *not* guaranteed

Hey guys, unpopular opinion, but I think zombie media (games, movies, shows, etc.) would be a lot scarier, more tragic and impactful if a zombie scratch/bite is not *guaranteed* to lead to a turning, just often.

At the moment, the problem with zombie media is that it can be very suspenseful right up until the point that a character is bitten, because then you know exactly what will happen. If you were to change that, you keep the suspense much longer.

That way, the trope of "oh no I've been bitten better keep it hidden" also actually makes sense - you're bitten, but you have hope you'll just fight off the infection. You start to show symptoms but will you or won't you? And when your fellow survivors find out, will they take the risk? Or go for maximum safety?

when you raid that house and you see someone with sores, open wounds, and the like, are they actually a zombie? or are they a survivor with severe but survivable symptoms? did you defend yourself when killing them on sight, or did you just murder an innocent who needed help?
