Jackal seems inherently as a hungry character to me. Starving in the sense that he wants a relationship and companionship so much that it blinds him. And well, Hunger always leaves you a little less of yourself.
It's dehumanizing because when you're so desperate for something it breaks down the human and logical sensibilities and leaves something animalistic behind. This is where the animal metaphors that the show is so heavy with starts to hit too close. The Jackal is portrayed as such an inhumanly perfect character that when he does show humanity in a desire for someone to know him truly as himself and not just as another mask, he portrays even this snippet of humanity inhumanely if you get what I mean?
His role is inherently inhuman, eldritch and odd in the way that you'd expect an old-time God to be cold and distanced with a confusing sense of empathy entwined with a longing for something that fate would never let him have. But instead of bringing more humanity into his character, the extent at which this longing hits him just drives him back into a different type of inhumanity that leaves him something like a starving animal
