The funny thing about Equinox is... flash back to Year of Hell, when -her- ship was beat up and they were desperate. She was acting borderline insane at times, acting rashly to the detriment of the ship, threatening to delete the doctor and so forth. Suppose she ran into those space slugs there, would she have hesitated to use them? I don't think so.
Heck, her whole condemning of Ransom and his crew was a case of the pot calling the kettle black. At one point she was basically saying, "I'm going to kill you if you don't betray your captain to me and help me hunt him down and kill him... because he's betrayed our high moral values!" Riiiiiight... even wooden prop Chakotay calls her on how nuts this is and has to stop her from executing the guy... and gets relieved for doing the right thing.
