What is the theme in Anna in the Tropics by Nilo Cruz?

Violence versus Reason is a major theme of the play. The opening scene of the play contrasts two approaches toward life, one violent and the other reasoned. Violence, as depicted by the savage game of cockfighting, suggests that skill, cunning, and might will always win. Although Cheché is a cautious man when it comes to gambling, he embodies the idea that physical power will triumph if reason should fail to persuade. For example, Cheché takes Marela by force when she ignores his lurid glances and innuendo.
