Donalbain

Donalbain is the son of Duncan and the younger brother of Malcolm. After Duncan's death he decides to flee to Ireland, fearing for his life. Many blame him for parricide because he left in a hurry, putting the suspicion onto him. However, we never hear from or about Donalbain for the rest of the play, and it seems that since he has fled he is being very cautious in coming back to Scotland, as he never does. Donalbain leaves Malcolm because he believes that their "separated fortune shall keep us both the safer".
