My clue to God controlling the plays  fate, is that when Mercutio dies he puts a curse upon the two households. Which also shows that in the prologue when they say that Romeo and Juliet are going to die<span style="color.So I think what Shakespeare is trying to say is that God is given a power to make choices but Mercutio still cursed upon them so Shakespeare is showing that god will accept the death wish and will actually curse upon the 2 Households.
