The passage shows how Romeo matured when it shows that he began to understand how other characters' feelings worked and that it didn't make them worse or better.
In addition, he remains unchanged or shows that he has a certain hurt about the events that happened in the past.
<h3>Why Romeo needs to show maturity</h3>
Because he's a very young character.
Because he's a very emotional character.
Because he was shown to be very impulsive and not rational.
Romeo used to care about his feelings and as he was very emotional, he used to act impulsively, not caring about understanding the people around him.
He shows that he has matured and started to be more rational when he shows that he understands Prince's actions, even if he doesn't agree with them. However, he shows hurt over Mercutio's death, which underscores that he is still the same Romeo as before.
