Kilgrave puts his life in danger, by having his father administer a full (possibly lethal) dose, because he remains a powerful man with the smallest of ambitions.
That's kind of cool, in that Kilgrave is like Jones and Cage, in that respect. All of them are 'sub optimal' in the exploitation of their abilities potential, either being more or less unwilling heroes, or a kind of half-assed supervillain who'se more interested in getting fed and laid, than in becoming a multi-billionaire and moving into the White House.
Kilgrave has abilities that give him potential that leaves someone like Jeri Hogarth supremely frustrated, because they aren't doing the sort of crazy things *she* would be doing with them.
Of course, having that power available, seems to have robbed him of any real lasting satisfaction from the things he can take, and left him obsessed with the one thing he *can't* just take, love and affection, freely given, from a woman he isn't mind-controlling.
