How does Prince Prospero exhibit pride in "The Masque of the Red Death"?

Prince Prospero demonstrates his pride by thinking that he can outwit death and avoid becoming a victim of the devastating contagion known as the Red Death. In an astonishing show of hubris, Prince Prospero invites a thousand aristocrats to stay in one of his castellated abbeys, which is securely locked to prevent people from entering or leaving. Inside the abbey, Prince Prospero has a massive amount of food and resources to survive for an extended period of time inside the walls of his abbey while the Red Death wreaks havoc upon the countryside and continues to devastate the population. Prince Prospero not only believes that he can outwit and survive imminent death but also engages in revelries inside his walls as a way to mock death. The prince even holds a masquerade ball, where there are seven colored rooms in his imperial suite, where his bizarre-looking guests dance and drink. When the Red Death enters the masquerade, the prince once again displays his pride by attempting to kill death itself as he brandishes a dagger. However, Prince Prospero becomes a victim of his own hubris and dies at the feet of the Red Death in the seventh room of his imperial suite.
