he's only been awake for hours that means he's only been a vampire for a couple of hours his way of thinking should still be human ...
... it is true vampires do think of humans as food but that's only because they've been vampires for a long time
they developed that way of thinking over time
Those statements are not absolutes of vampire lore though. Which I think you understand as you later say...
I do agree with you with that a lot of vampires Act
the way you described
As examples from pop culture, in the WoD, the predatory "beast" is immediately in the soul of newly made vampires and they constantly feel it's tug, and the Whedonverse has a demon share/take over the mindset of the person immediately upon conversion. An alternate historical take on it, IIRC some of the Eastern views on vampires revolved around the vampire essentially being a spirit infesting the body of a deceased person, not even the original person anymore, anything human in it's memories nothing but knowledge the spirit could draw from to mimic being human from an otherwise inhuman mindset.
It's also not uncommon in vampire stories for vampires to commit atrocious deeds by compulsion... and then have to deal with the morality of what they've done after they're sated and their senses are less controlled by their compulsion/addiction. If something a reader sees makes them go "I'd hate doing that, why would I do that", well, in those takes on the lore, that's EXACTLY what the vampire is thinking after the act when they come to their senses. The uncomfortableness is key to what's happening and possibly the feeling the author specifically wanted from that scene.
Which is not to say there aren't takes on vampirism where the human side is more a factor, Forever Knight comes to my mind first, lol that's been awhile, or even going back to the WoD there are many vampires that work hard at being humane, and in fact can end up more 'human' than most humans. The idea that a vampire is just a human with neat superpowers and particularly bad sunburns can work! One of the coolest vampire movies I ever saw, and damn if I caught the name, involved Dracula making amends for centuries and in the final scene, saving humans from other vampires, he's exposed to the sun and the cross expecting to die but unlike all the other vampires he doesn't burn since God forgives him since his redemption was complete to the point of sacrificing/giving up immortality just to save regular people. Yes, vampires acting human can work.
But it just may not be the take this author is giving it and if it's not they shouldn't have to PG-13 something like vampires which, by their nature, are a somewhat dark concept. Though, more to what I think we both agree on, it would optimally be a choice left to the player if the rest of the narrative can be interpreted either way.
