...If you love her then, tomorrow wed her. But it would better fit your honor to change your mind.
Go but with me tonight, you shall see her chamber window entered, even the night before her wedding day....
May be this so?
Is my lord well, that he doth speak so wide?
Not to be married, Not to knit my soul to an approvèd wanton.
Don John and Don Pedro Don John, Don Pedro's brother, was envied his brothers power. He hated the fact the Don Pedro had control over him. Because of this conflict, he planned to cause chaos and take over the power of his brother.
At this moment, Claudio goes through an internal conflict whether he has to trust Don John, who is accusing Hero that she cheated on him, or Hero, who is Claudio's deep love. Claudio starts to distrust Hero just with Don John's deception.
The conflict between Claudio and Hero intensifies, and Claudio's distrust on Hero has reached the point where he refuses to marry her.
Benedick and Claudio are good friends, however, they share some similarities and differences. Unlike Claudio, who falls in love fairly easily, Benedick is very careful. He says that he will never fall in love, and swears that he will die a bachelor. When Claudio first saw Hero and fell in love, Benedick was not impressed, but instead, he criticized her like he does do every women.
However, Benedick's promise did not last for long. After listening over to a conversation that Beatrice loves him, he falls in love with her. Just like Claudio, he fell in love fairly easily. Even though he fell in love with Beatrice in a similar way Claudio fell in love with Hero, Benedick's love was way more truthful than Claudio's.
Benedick shows his true love to Beatrice when Hero fainted after being called a whore by Claudio. Beatrice tells Benedick that Hero is completely innocent, and he straightaway believes her. Since Benedick truly loves Beatrice, he trusts her, unlike Claudio, who still managed to say that Hero is guilty despite the fact that Hero denied the rumor. Also, when Beatrice asks Benedick to kill his best friend Claudio if he really loves her, he goes to do so, showing his true love.
