I'm looking for an adjective that means the person described has the power to choose their own actions, rather than being someone else's puppet. "Potent" is the closest I've come but it's not right.

The context is a reaction I'm writing to the Conquistador Bernal Diaz del Castillo's account of The True Story of the Discovery and Conquest of Mexico, in which he describes certain actions on the part of La Malinche, an Indigenous woman who served Hernan Cortez as interpreter and concubine, and was a Christian convert. The discussion is about how realistic Diaz's portrayal is, specifically regarding a passage where Cortez's party visits the town where Malinche had been given by her family to human traffickers years earlier, and Diaz, retelling the events 50 years later, says Malinche forgave them, gave them unreasonably fine gifts, and sets for them a Christian example of devotion to her new Spanish husband (not Cortez, someone else), no doubt with proselytizing intent.

What I'd like to say with a single adjective is something that conveys autonomy on her part, independence, initiative, freedom from the influence of the soldiers she came with. Is there a word related to "possessing agency" which fills in this blank?

"I'm not generally a cynical person but regarding the Conquistadors and the Church, you don't even have to be cynical to recognize that they embellished their writing, and Christianizing an Indian woman and making her out to be more pure, forgiving and _______________ than realistic makes the Spaniards look good."

Words which don't fit because they either don't capture the whole connotation or are too tortured to sound reasonable include: Autonomous, potent, vital, independent, self-actualized, agency-having and so on.
