If that is true (Kaneki gaining the personality of the people/ghouls he eats), it is a plausible theory; when Kaneki "ate" Rize, he gained enormous strength, hightened speed and less susceptible to pain, characteristics of Rize in the series. When he ate Jason, he became a sadist, and adapted the habit of cracking fingers. When he ate the test subjects, he lost all his sense of reasoning, due to the test subjects' failure and unstable mind, making him a Kakuja. Kaneki's sanity only restored when he wounded Banjo, who is a good fellow, a close friend of Kaneki and protector of the weak, so maybe he adapted to the traits of Banjo, even without eating him. It's just a theory, though.
