These actions include murder. Both men become villains in different ways - Richard seems to have been born villainous and Macbeth seems to prove that villains are not born but made from outside influences. Shakespeare proves both assertions valid when we see Macbeth reach the same level of conniving and ruthlessness as Richard. The dream of power and the intense thirst for ambition lead both men to murder. In addition, both men not only murder but also commit cold-blooded murder to get what they want proving that we are not so different from one another.
