The men in THT have the "freedom" of movement, e.g. they can drive. Women have to be driven. Men have access of resources: cars, bikes, jobs, money. Women can only receive what they are given. If you have nothing, and have no freedom, from a pragmatic viewpoint, you have no ability to rescue.
But despite this you see acts of compassion amongst the women at times.
If you have few choices, and access to few resources, then you have to compete to survive. It's primordial. The rules were developed by men, leaving the women to fight for scraps. And fight they will in order to access more: more status, more freedom, more comfort in order to secure better chance of survival.
AL may utterly believe in Gilead - because it has given her something (power, contol, status), which she did not have before. She will do whatever it takes to protect her interests. That is how her esteem and physical being survives. That means she will inflict heinous suffering on others. Her survival is dependent on being able to do so - there is also an absence of choice for her. She, therefore, is "rescued" by the system that simultaneously has imprisoned her gender.
It's patriarchy at it's most extreme: women can only get what men deem to give them. The men will retain the bulk of the resources and freedoms for their own survival. Trading only when necessary, and only on their terms.
Simple human economics in action.
