The name of the narrative is "Resistance to civil government (Civil Disobedience)" by Henry David Thoreau.
In his essay, David Thoreau described that individuals shall not give the Government to overrule their consciences. Because if people as a society allow this, we basically allow the Government the power to do injustices without any consequences.
MacBeth attempts to resolve his conflict by doing the act again. He is consumed by guilt and anger from killing the king that he ends up killing another. This only makes him worse and throws him into the path of evil and tyranny.<span />
