The Road Of Bloodshed In Shakespeare's 'Macbeth'

Macbeth was saying that since he has started on the road of bloodshed, more is bound to come. He is saying that there is no real way to stop bloodshed because in order to stop it from happening you have to have more bloodshed. Those Macbeth has murdered will have their revenge in the end, as things will come back to him in the end. He thinks that more bloodshed needs to happen and he needs to get rid of more people so that his plan does not go downhill. He believes that the road he is on will not end without more bloodshed and that more will happen along the way. He thinks he needs to be cautious about the people around him now and be sure that he can actually trust them.
