Can anyone check if my English grammar is right?

In the film, I identified aggression from the Russian boy from the Popov family. The boy's behavior was always intended to hurt and argue with his father. He wouldn’t stop until he felt he won the “fight” This boy was always showing his disrespect towards his father, and his father reinforced the aggressive behavior with attention. He often threatened his father verbally and physically even with simple kicks. His reaction was due to the arrival of his new brother and the fact that he felt that he didn't belong in the family.
