What does the old man want to do? Chapter 44-46

In Chapter 45, Elías meets with an old man named Captain Pablo, who he tries to convince to travel north with him to live together as makeshift father and son. Pablo refuses, however, and tells his story: a minister raped his daughter, then framed one of his sons for a robbery and tortured him to death, fearing that the sons would take revenge on him, while the other son was arrested by the Civil Guard and harassed until he committed suicide. Pablo explains that he has joined with others who have suffered similar abuses of power and is planning revenge.
