Infected Werewolf Who Has Retained Control

He was born a human but was bitten by a werewolf and is now cursed to take the shape of a humanoid wolf during the moon. But somehow he has retained his humanity and even gotten control of his transformation into the beast and back ,though during the full moon he cannot shift back unless the moon is covered. Even though he is more animal in his mind then before has he retained most of his human rational thoughts and moral codes, but he has the mentality of an animal also, making him far more unpredictable then he was as a human. There are possibilities that he may submit to his inner beast in some circumstances or maybe even intentionally submit to the beast for some reason.
