One example that you can pick is the conflict between the individual and the social. Your main argument could be that Shakespeare was trying to show how tragedy usually occurs when people care only about their individual desires and not about their society.
In terms of the individual, the most obvious example is that of Romeo and Juliet. They are ready to follow their hearts and think only of themselves, regardless of what their families and societies suffer from it. Montague and Capulet are also being selfish and only thinking about themselves when they maintain their hate for each other, regardless of the harm they cause to Verona.
In terms of the social, we can show the Prince. If the Prince had intervened and protected society, many tragedies could have been avoided. Capulet and the Montague, as well as Romeo and Juliet, would have also been better off if they had cared more about the social consequences of their actions.
