Hello. You did not enter the text to which this question is related, which prevents it from being answered. However, I will try to help you in the best possible way.
It is only possible to answer your question by reading the play completely. By doing the reading you will be able to identify the themes that the play presents. These themes are the main subjects covered, that is, they are the subjects that the author wanted to expose during the exhibition of the play. "Romeo and Juliet," for example, portrays themes such as the inevitability of fate and the violence of forbidden love.
In this case, by recognizing the themes presented in the play, you will be able to identify how Friar's behavior, in the play that your question refers to, manages to address these themes. Using "Romeo and Juliet" as another example, we can see that when helping Romeo and Juliet, Friar Laurence addresses the theme of the inevitability of destiny, as he believes that it is the destiny of young people to be together and that is why he decides to help them.
