It's a great episode precisely because
it's a female vowing revenge and not Trek's standard stereotype of the out-of-control, Ahab-like male -- and let's face it, because her primary motivation is
revenge and not
protecting the Federation or its citizens, her actions are not heroic but selfish and personal. Like Matt Decker, she gets some sympathy for the tragedy of the events, but like Matt Decker, she is less than noble.
