What is an appropriate thesis statement for “the role of frair laurence in romeo and juliet”?

  Fray Lorenzo is a fundamental character in the tragedy, he is a caring and kind person, with neutral behavior towards the two opposing families. He is a practical and intelligent person, always ready to help Romeo and Juliet with his love, He constantly gives advice to both of them on how to act with more moderation and caution. In his desire to end the rivalries between the Montagues and the Capulets, he agrees to marry the couple effectively and quickly to the rhythm of the frantic love of Romeo and Juliet. However, Fray Lorenzo's plans to help them end in tragedy, since he was the person who created the tragic plan of Julieta's simulated death, thanks to his knowledge of alchemy and the handling of concoctions and potions.
We could say that Fray Lorenzo is the person in this tragedy that will direct and / or influence the unfolding of the facts, the decisions taken by him, without wanting it, will result in the tragic consequence of the death of Romeo and Juliet

Ibelieve he answer is a, but correct me if i'm wrong.
