probably out of a sort of subconscious self-loathing. Kilgrave is himself a child, someone who has never heard the word 'no' in his life and never had to develop emotionally from 10 when his powers came in. The idea of someone else's feelings mattering, the concept of "sitting around
hoping people will do what you want them to do", is entirely foreign. His fixation with Jessica is solely because she was the only person in however many years who ever refused him, and that's a shiny new interesting thing he desperately wants to play with.
Moving into Jessica's house, replacing
everything exactly as it was based on obsessively studying realtor photos, is obviously creepy to Jessica and anyone watching. But he genuinely doesn't see it that way. He thinks he's being romantic. He thinks this is what Jessica will like. He pitched a full-blown
tantrum in the police station when someone 'ruined' the mood while he was trying to "profess eternal love". He thinks paying the staff handsomely then holding them hostage on threat of death is
totally different from using his powers on Jessica, suffers their mere presence at the dinner table solely because Jessica asked him. Saw absolutely nothing wrong with making the crazy father blow his own head off, and all he took from the 'heroism' thing was the ego-stroking rush of the mother thanking him. Remember, he murdered the
shit out of Reuben because he dared profess love for Purest Waifu and therefore he just had to go. He didn't even have to say anything. The sheer "you gon' git it now" in his face before the scene-change said volumes.
Kilgrave is a warped, emotionally-stunted narcissist. He's offended when Jessica says he raped her because, well, there was no roofies or back-alley struggles. He takes his 'girlfriends' out and shows them a good time, fine dining and nice things. He had fun so they,
obviously, had fun too. Then he moves on, and never has to confront the fact that other people have lives that are ruined by what he did. Hell, in a way he gives women
preferential treatment. At least he never said "leave your son on the kerb and drive off" or "beat your head on this post!" to any of his girlfriends. Of course Jessica's accusation would completely nonplus him. Especially since he 'fixed' his behaviour so
obviously she has nothing to complain about any more, right?. His behaviour really has more in common with the 'billionaire playboy who lives by his own rules' archetype than a fat neckbeard sitting in a dark basement rubbing his hands and disdainfully muttering "
women".
And even though his version of his backstory turns out to be warped too, I don't think it was all an act. David Tennant seems to play it like
Kilgrave believes it. His anguish at seeing his parents again is entirely real. It
would suck to grow up with those kinds of powers, powers you have absolutely no control over but for exactingly careful word-choice. His vocal stumbles when buying Jessica's old house may be comedic but the fact that he faced that his entire life doesn't make it hard to understand why he eventually just gave up trying to avoid it. And in the end his parents
did abandon him rather than try to help their son, blamed him for it all and ran.
Plus Jessica does, like,
actively torture him. Even if he is a monster, what she did to him was kind of fucked up. Especially because she got less than no results.
But hey maybe I'm wrong and sometime in episodes 10-13 Kilgrave will suddenly blurt out "IT'S ACTUALLY ABOUT ETHICS IN MARVEL COMICS, GO HOME GAMERGIRL" and yell at Female Thor for being a feminazi while posting mean things on Twitter and ordering Dead Or Alive Xreme 3 on Play Asia while Trish dramatically says "
he levelled up"
