This dissertation centers the lives of Spanish-speaking migrant women and their ethical navigations amidst violent systems to construct an ethic of migration. Violent systems signify the circumstances that force women to migrate, the impossible moral demands they encounter, and the political environments that burden their agency. I place my community partners in conversation with discourse around 1) moral luck; 2) the burdened virtues; 3) and buen vivir, an Andean and Amazonian indigenous ethic. I explore how migrant women’s faith and ethical negotiations reveal previously unconsidered agency. I employ an emic ethnography of group and individual interviews of fifty women and contribute my story of survival after migration and assault. My partners recount how they navigate through fraught moral choices and multiple responsibilities in contexts of abuse, poverty, and exploitation. They relate how they lived with their decisions amidst trauma and agent regret. They testify how they found their moral agency. Three virtues are evident thus far: reciprocity, care for the land, and resourcefulness. These are reflected in an indigenous ethic of buen vivir, defined as a flourishing-in-relationship among humans, animals, and nature. My dissertation interrogates systems of violence that burden virtue and provides narratives of agency that can advise ethical migration policies and theologies.
