What the Chorus Leader assumes to be the reason for Antigone's decision to go against her king is that she is Oedipus' daughter and she can't help herself because of bitterness. She decided to disobey Creon's orders and wanted to give her brother a proper burial even though he is a traitor to the state. The king didn't want him to be buried, but rather to be left to the dogs to eat him, however, Antigone never wanted to let that happen.
