Women express their revenge fantasy in different ways. Instead of beating his opponent up or shoot him at point blank, women prefers psychological torture: boiling her rival's favorite pet rabbit, making her witness her son's asthma attack without recourse, in order to break down her sanity and makes her wish she were dead. (Incidentally this is why I loathe Korean revenge cinema: this is where men behave like women and women behave like.... I dunno... caricatures?)
Or, if you want a real-life example, look at Zoe Cunt.
