The scene starts of with a soliloquy by Macbeth on whether he should kill King Duncan or not and at the end of the soliloquy he has still not decided to go on with the murder. Then Lady Macbeth comes and persuades him by teasing him and questioning his masculinity, to change his mind. Finally he changes his mind and is ready to kill King Duncan. A quote to prove why he thinks he shouldn’t kill Duncan ‘Could trammel up the consequences and catch.’
