For Romeo and Juliet, how did Shakespeare set out one of the play's major themes - the conflict between love and hate?

That is new vs old generations because the old want to stop the war and stop fighting because of their age. But the new generation wants to keep the fight going. He applied love with Romeo and Juilette (obviously) but also with their falilys when they died. Because all of a sudden both familys start to care about them. So you can see shakesphere is good at themes and what your post to get of it
