One of the themes of the play could be said to be "Death in Life", that is how people can 'die' while they're still alive. At one point in the play, the Mother asks the Bride: “Do you know what it is to be married, child?” The Bride says she does, but the Mother emphasizes her point anyway: “A man, some children, and a wall two yards thick for everything else."

At this point, we can see that a Boda de Sangre (Wedding of Blood) could be seen as a jumping off point for death, rather then a celebration of life. Marriage as a social institution can cause an early death while one is still alive, while true love can reaffirm life.
