One of the methods often used to integrate a rape storyline into a show is as a tragic backstory – a flashback used to explain why a woman is the way she is, particularly if that woman is of the colder, less trusting variety. The Americans did this with lead character Elizabeth Jennings, a Soviet spy undercover as a normal American citizen. In the pilot of the series, during a flashback, we see a young Elizabeth preparing for her future role as a spy and subsequently being assaulted by a commanding officer. 

Villainous women have existed in fiction for as long as there's been fiction, though they often fall into types: mean girls, evil queens, harping wives, revenging mistresses. Often, they all share one quality: they are unsympathetic. This is not a sweeping statement across the board, of course, and characters intended to be unsympathetic can be read sympathetically by certain audiences. However, female characters of questionable morality are not always granted the automatic sympathy of a lot of their male counterparts. Men can be antiheroes; women often aren't allowed that luxury.
