Answer: Creon
Creon is Antigone's uncle, and a recurring character in Sophocles' plays. Creon is an example of an archetypal villain. Although not truly "evil," Creon is pushed to commit acts he would normally be opposed to due to how highly he values the throne, and his responsbilities to the citizens and the law. He is pushed to be the villain out of circumstances, rather than because of an evil heart, which is a common story for literary villains.
