Well for one I think their immaturity didn't help the situation. Their love was a lot like puppy love in the sense that it was their first time dealing with a relationship and therefore didn't know how to handle issues that were thrown at them. At the same time, some of the other characters may disagree because "young love is the best love" in the sense that it is pure and innocent.
Faith require someone to act or follow rules no matter what the situation is.
If several people have different faith , and their faith contradict each other (what person A believe is considered a sin by person B's faith), this will potentially caused conflict that may harm them
hope this helps
