It's a tragedy. The main character or characters always die at the end of Shakespearean tragedies.
In the internal logic of the play, Macbeth has to be deposed to end his reign of terror, and that can only happen if he is killed. Besides, Macduff wants revenge for the death of his family.
Macbeth is killed at the end of the play because he is defeated in battle by Macduff, who reveals that he was not born of a woman in the traditional sense. Macbeth's death serves as a result of his tragic flaw of vaulting ambition and the consequences of his ruthless actions throughout the play.
Just about nobody is loyal to Macbeth at the end. Seyton (sounds like Satan and who knows? it might be him) is one of the last to stay with Macbeth.
