Describe Iqbal's behavior at the train station

Iqbal surprisingly happens to be one of the mobsters who rudely confronts the narrator’s father. Iqbal violently mocks and abuses his dear friend in an attempt to protect him from other mob members who were hell-bent on physically harming Hindus. Iqbal secretly puts money and a letter in his friend's pocket as he throws him onto the train. Iqbal had so much love and respect for his friend that he made it his mission to ensure he left Pakistan safely.
