Who is the main character in "The Masque of the Red Death"?

In The Masque of the Red Death, the main character is Prince Prospero. The prince is described as "happy and dauntless and sagacious" by Poe, but he is also at least a little naive and slightly irresponsible. While his kingdom was being terrorized by the Red Death, when half of his people had been killed by the disease, he gathered one thousand of his friends and retreated to an abbey in order to escape the plague—by doing this, he is abandoning all of the people who were still alive. Thinking that he could just ignore the disease and throw a party to forget their troubles is naive; the concept of "if I can't see you, you can't see me" is a childish one, and that seems to be exactly what Prince Prospero is trying to accomplish: if he cannot see the plague and its devastation, then it does not exist. His irresponsibility is shown in his abandonment of the people—the same people he was in charge of.
