It is fascinating to examine how each of the four sisters responds to the terror of the Trujillo regime. Minerva, out of all of them, is the first to be involved in the rebel movement, thanks to her friendship with Virgilio Morales. Part of her character is her headstrong defiance of Trujillo's regime, and the way that she is able to face Trujillo without yielding. Note how she refuses to give in to Trujillo's sexual advances and then how she challenges Trujillo and gambles for the right to study law. Clearly, as it says in the text, she sets herself in opposition to Trujillo:
I look down at the lopsided scales as he puts his dice back. For a moment, I imagine them evenly balanced, his will on one side, mine of the other.
As her mother has already noted, Minerva is determined to "fight everyone's fight," even though this endangers the situation and lives of her family and those nearest and dearest to her. Unfortunately, although she did not desire it, part of being a rebel is the way that your actions endanger those around you, and thus Minerva does cause harm to others through her rebel associations.
