What would make D feel jealous? I know in the first anime movie, Lefty comments on how D may envy warmth shared between humans.
There is some envy there, but D’s been at his mission so long that it more than likely doesn’t bother him enough anymore for him to really care. Along with the fact that his personal wants and desires are outweighed by the mission’s importance.Going more by the books than the movie as the OVA took some liberties with the source material, I believe it’s more of him being a little envious that humans have the choice to share their lives with another versus actually doing it, because they have the freedom to do so. He can’t be as carefree… He doesn’t have that luxury.D set himself on this quest to find Drac and end the Nobility, like this is his responsibility and he feels like he’s the only one that can do it - and truly he is the only one that can do it. No one else is strong enough. In doing so, it was a necessity to become a hunter - this sort of quest is going to require money obviously. As such, D believes he doesn’t get to choose. “I don’t get to have a life…” But it’s more than just because he’s a dhampir…more like because if he were to decide to do otherwise - to be like “Fuck it. I don’t want to do this anymore… I’m lonely… I want the kind of life everybody else dreams of and gets to have” - that would doom the whole of humanity.You could say he’s kinda like the titan, Atlas, although this is a job he took on himself rather than a punishment, but the notion is the same. He bears the burden of responsibility to be humanity’s protector and forever roam the globe taking out the monsters that want to oppress them.A long winded way of saying D is a little jealous that others get the choice to have a life…and gets annoyed when they choose not to because of reasons he feels are easily fixed, like ‘blood on their hands’. ‘Wash them’, he says… 'just wash your stupid hands…’Then there’s him being a slightly competitive brat… Yeah, I said it. He’s competitive. Journey to the North Sea, when Ban'gyoh gives that boy a better looking flute to play with over the one D made… I swear he’s like, “Fuck you and your dumb flute…how dare you be better than me…” And then essentially gloats when the kid comes back asking for that handmade flute because the shiny one broke too easily.
