When making decisions, does Friar Laurence in Romeo and Juliet, rely on logic or emotion?

Friar Laurence generally chooses logic over emotion, but he is not devoid of feelings. He is quite wise, observing that “Virtue itself turns vice, being misapplied,” unwittingly predicting how his good intentions will lead to the deaths of Romeo and Juliet. He tells Romeo to take his time and think: “Wisely and slow; they stumble that run fast.” The friar is thoughtful and observant, correctly assuming that Romeo has been awake all night when he greets him at such an early hour. Even his decision to wed Romeo and Juliet is not purely driven by sentiment but by a desire to unite the Capulets and Montagues: “For this alliance may so happy prove, / To turn your households' rancour to pure love.”

However, the friar also exhibits emotions. When Romeo tells him his love has abruptly shifted from Rosaline to Juliet, the friar exclaims, “Holy Saint Francis, what a change is here!” and “Jesu Maria!” He appears to lose his temper when Romeo attempts to stab himself, declaring, “Hold thy desperate hand: / Art thou a man?” Another time when instinct overrules logic is when Friar Laurence finds Romeo’s and Paris’s dead bodies. He panics, suggests that Juliet become a nun, and flees without Juliet when she resists. A watchman says that the friar “trembles, sighs and weeps.” Friar Laurence then begs the prince for death. Therefore, even though the friar is a very logical individual, he cannot help but be overcome with emotion from time to time.
