Did this character experience any growth or changes during the story (explain)?

Claudio's youth and immaturity are evident throughout the majority of the play. He loves hard, hates with all of his being, makes rash decisions, and is mercilous with his friends. His emotions don't just sway back and forth like a pendulum; they crash like a wrecking ball from one extreme to the other. Claudio displays poor judgment, is easily manipulated, and doesn't know the definition of modesty. Thus, it is well for him that by the play's end he does somewhat redeem himself of youthful folly by learning to apologize if nothing else. As a character, he has hope, but I wouldn't count on it.
