Was Salim considered a good or bad brother? only one side.

Salim isn's just a questionable character, he is a bad brother. He is unable to see beyond himself, and his desire for power and wealth..... even if it means selling out his brother. While Jamal resists the life of a gangster, the easiest way to self-improve from slumdog status, Salim embraces it. At a young age, he picks up a revolver and kills Maman, a gangster, and from this moment on, he becomes a gangster himself. Salim and Jamal have a complicated relationship, and Salim betrays him at various moments. However, he atones for his errors at the end by sacrificing himself to free Latika.
