Names for a character?

This character lives in 1810 South Carolina. He is from an exceptionally wealthy family of plantation-owners. He's also very good-looking, with long blond hair that he normally ties back, brown eyes, and slightly tan skin because he loves being outside. Needless to say, since he's about 20, rich, and handsome, girls love him. On the outside, his personality is very charming and flirtatious and almost cheerful. However, he has a much darker side to him. He can be very cruel, stubborn, and extremely overprotective. He does the wrong things for the right reasons, meaning that he tries to do the right thing, but goes too extreme with it. It's also very easy to make him angry. Names for this complex character?
