The moment that breaks Jem's remaining code of childhood is when he destroys Mrs. Dubose's camellias.
Here's why this act is significant:
* Loss of Innocence: This act marks a turning point in Jem's understanding of the world. Up until this point, he's maintained a somewhat innocent perspective.
* Breaking the Rules: Jem, under the influence of anger and frustration, acts impulsively and breaks a rule (respecting someone else's property). This signifies a shift towards a more mature and complex understanding of right and wrong.
* Facing Consequences: Jem is forced to face the consequences of his actions, including an imposed punishment and the realization that his actions have hurt someone else. This experience contributes to his growing maturity and a deeper sense of responsibility.
* Understanding Complexity: This event opens Jem's eyes to the complexities of adult relationships and the presence of difficult emotions like anger and resentment.
This incident represents a key moment in Jem's journey from childhood to adolescence, where he begins to grapple with the complexities and challenges of the adult world.
