In Act Two, Scene 2, who seems to be more courageous, Macbeth or Lady Macbeth?

In Act Two, Scene 2, Macbeth exits Duncan's chamber and tells his wife that he committed the murder. He is clearly shaken and laments about his actions. Macbeth looks down at his bloody hands and says "this is a sorry sight." Macbeth then tells his wife that Duncan's chamberlains woke each other up when one cried "Murder!". They then blessed each other and Macbeth comments that he was not able to say "Amen." Macbeth goes on to tell his wife that he heard a voice say "Sleep no more!" and Lady Macbeth responds by telling him that he's allowed himself to become weak and cowardly. She then tells him to wash his hands off and calls him a coward for not placing the daggers by the chamberlains. Lady Macbeth then takes it upon herself to enter Duncan's chamber to put the daggers in their proper place. Throughout this scene, Lady Macbeth clearly seems to have more courage. Unlike her husband, Lady Macbeth is focused on completing the task. She dismissed Macbeth's fears of hearing voices and told him to wash the blood from his hands. Lady Macbeth is level-headed, while her husband is shaken, confused, and full of regret.
