Quote #4
Even so, that night, her ears still ringing from Jaimito's shout, Dedé had been ready to risk her life. It was her marriage that she couldn't put on the line. (3.9.66)
All of the sisters must make sacrifices in order to join the movement. Minerva and Mate lose their freedom and Patria loses her son. But Dedé is the only one who doesn't have the support of her husband. It's easy to condemn her for cowardice, but she is the only one who is faced with sacrificing her marriage.
Quote #5
It wasn't just that she couldn't bear losing her boys, although that in itself was a dread large enough to stop her in her tracks. She also couldn't desert them. Who would stand between them and the raised hand when their father lost his temper? Who would make them mangú the way they liked it, cut their hair so it looked right, and sit in the dark with them when they were scared and the next morning not remind them she had been there? (3.9.121)
Dedé is being asked to sacrifice her marriage in order to join her sisters, but by doing so she would lose contact with her boys. She frames her decision not to join as a sacrifice: she must sacrifice her involvement in order to be there for her sons when they need her.
Quote #6
And Nelson and Pedrito, seeing the conflagration and fearing for Patria and the children, came running down from the hills, their hands over their heads, giving themselves up. (3.9.225)
Nelson and Pedrito could have escaped the horrors of prison if they had kept running, but they sacrifice their freedom because of their fear for Patria, Noris, and Raúl Enrique. They are willing to literally "give themselves up" because of the family ties they feel for the others.
