Why is curly so aggressive in the book mice of men?

Answer 1

Curley is so aggressive because he tries to look tough in front of the big guys and because he's small he's actually afraid of the big guys so he tries to look big by being tough. (he's small so he tries to look big)

Answer 2

Curley's aggression in "Of Mice and Men" is likely a reflection of his insecurity and need to assert dominance due to his small stature. He also uses his aggression to compensate for his lack of control over other aspects of his life, such as his troubled relationship with his wife. Additionally, his role on the ranch as the boss's son may have also fueled his aggressive behavior to maintain an image of power and authority.
