As Duke said, a slow evolution. When I started Pest he was very different from he is now. He went through a hardened child raping killer phase, then I recently started showing the ghosts of his past haunting him. Culminating in him trying to push his legacy of brutality on. Because according to his biography, which may be faked, brutality is what he learned. I've slowly changed him from hardened monster to a pained old man. Who still likes teenage girls.
