Chavez says this to Antonio's father. It's his argument as to why he, Chavez, can't simply let other men track down Lupito, the man who killed Chavez's brother. Right off the bat, Anaya starts to tie the idea of revenge with the idea of honor. Revenge, in most cases in the book, isn't just about violence or even over-reaction; it's about standing up for family and loved ones. Keep this in mind, because it plays out even in Tenorio's revenge, although honor gets a little twisted in that guy's mind.
