I think the most jarring part would be after waking up, seeing loved ones, passers-by, what-have-you...
...And not seeing them as people, but as a meal. The smell of them, that metallic tang. The sweetness and the tart. The heat rising from their skin. The sound of their hearts beating. Walking. Unaware.
Unexpected.
Prey.
All the while, part of your mind is screaming that this can't be true. It has to be wrong. It cannot be. But your id, your base desire, the dark core of you knows that it's true. It knows you're hungry.
While this may be true to some extent, one of the key differences that SR's vampires exhibit compared to many others is that, fundamentally, they
are still fundamentally human...psychologically, morally, intellectually. They don't have "Beast", they aren't soulless husks, they aren't demons jammed into the head of a now dead person. They're still (rarely meta)human beings, who have undergone a severely traumatic near-death experience (I say near, because while they did actually die, briefly, the Infection process revives them almost immediately and puts them in a coma while they change; their death duration is comparable enough to people that die on the operating table and are revived as to be indistinguishable) and now find themselves suffering from a horrific disease that has changed the way their lives will be until the day they die.
There aren't any voices whispering how tasty people look, you don't see people as walking milkshakes, and while your sense of smell is now supernaturally enhanced, it isn't fixated on BLOOD BLOOD BLOOD to the exclusion of anything else. There isn't even any concrete evidence suggesting that vampires suffer any higher rates of psychopathy or sociopathy than the population as a whole.
Now, that's the "base facts". How people that have been vampirized come to behave based on their experiences are another story. The fundamental issues involved with needing to drink blood and drain essence are going to do a massive number on the mind of any healthy person (the average vampire that didn't have issues before their infection). Long-term rationalization, desensitization, and post traumatic stress reactions will shape many vampires into seemingly "inhuman predators" as easily as they will combat veterans that can kill someone without seemingly any qualms. These reactions will often be even more pronounced in vampires due to the fact that society deems them monsters without any hope of redemption, to be hunted down and killed for the good of all. The construction of an identity reveling in that very monsterousness they're accused of is an easy defense mechanism to seek refuge in for someone on the edge like that, the classic "FINE, THEY CALL ME A MONSTER THEN A MONSTER I SHALL BE" reaction so often seen in people put into highly stressful environments where they're heaped with scorn and labeled as something terrible (criminal, thug, bully, "baby killer", etc). Should they actually kill someone, those behaviors will likely grow even more pronounced, as they face the fact that they actually HAVE done something they may have believed warranted being "hunted down" in their pre-Infection perspective. The struggle to remain a decent person as a vampire should BE a struggle, not against some supernatural urge or overwhelming predator's instincts, but against the same sort of inclinations and damages that produce entirely non-supernatural murderers.
tldr; vampires aren't monsters because they're vampires, they have the potential to become "monsters" because being a vampire means doing the same things mundane "monsters" do.
I firmly believe that being a ghoul or a vampire or other non-feralized Infected shouldn't profoundly change your personality or psyche in any "because you got infected" inherent way. The fact that they're still the same person they were beforehand just make far more interesting and morally complex, whether they DO wind up becoming irredeemable monsters or they remain (or even become for the first time) relatively decent human beings. Both in terms of how they behave...and how others behave toward them.
(Post not directed squarely at you, Doc, it's just that your post offered a good springboard to offer my own thoughts.)
