Feminists, similar to Marxists, view crime and deviance as a structure of power, where, how people are treated is based on what their economic background is or what resources they have. Or, to be more specific to this case, what gender they are.
When analyzing this topic, feminists primarily focus on how female perpetrators are viewed. They'll compare female and male convicts to see if society reacted with a double-standard, or if morality was used to blame a specific gender. They'll also look to see if the motive of a crime was to show power or dominance over another person.
