How did Black Dogs addiction affect people around him?

Black Dog is Uncle Bright Star's son. Black Dog has seen terrible injustices in America against Tang people and he has become bitter as a result. Black Dog has also become an opium addict. As a result, Black Dog will steal, lie, and cheat to get his next fix, even if it means cheating family. Black Dog steals from Moon Shadow and is the catalyst that forces Windrider to leave the Company the first time. Black Dog is also the reason Windrider cannot pay his rent at the end of the book, leaving him destitute and forced to abandon his dream after three years of hard work. In the end, Black Dog is found murdered in Oakland before he was even able to spend Windrider's money.
