He was a nobleman of Scottish origin. He has been opposed to Macbeth being king. He has a strong character because he does not hide the fact that he is opposed to Macbeth’s kingship no matter the consequences. This leads him to form a team that seeks to get Macbeth out of power, despite knowing how dangerous this task is. He initially appears to be supporting this cause because he believes that Malcolm should be the right king but it later emerges that his desire to get Macbeth out of the thrown is largely motivated by the need to avenge the death of his wife and son.
