Answer:
the difficulty of making moral judgments
passion as a motivation for hate and love
loyalty to true feelings versus loyalty to family expectations
Explanation:
Romeo and Juliet make numerous bad decisions for being in love and blind to everything else. Romeo is even alerted by his friend that he is basically someone else entirely since he fell in love with Juliet and is doing it all out of a insane hope of "having a hole to hide his toy in".
The foolish behavior of Romeo and Juliet creates many different reactions throughout the play. Characters that see their love as pure and want to help, and others who don't understand and want to put an end to it.
There's also the fact that their families never really approve, and would never, to the point of people even dying; all because they want to be with each other despite all the consequences.
