The Candyman has a tragic back story. He was a black man, an artist named Daniel Robitaille in the 19th century. He fell in love with a white woman, which was unacceptable at that time. He was brutally murdered by a racist mob. His body was smeared with honey, and he was stung to death by bees. His spirit then became the vengeful Candyman.
Sure. The Candyman was Daniel Robitaille, a black artist in the past. He was killed because of his relationship with a white woman and his spirit turned into the Candyman.
The story of Candyman is purely fictional. It was created to thrill and scare audiences through various forms of media like movies and books. There's no basis in reality for it.
