I don't know where this storyline comes from. There were only a handful of episodes where she broke her principles. Even then they spell out why. Couple times were when they fought the Equinox and she was basically trying to kill the other captain, even put her 2nd in command in the brig to stop him from trying to stop her. She saw he was killing off innocent, helpless aliens and wanted to take it out on him.
Another time was violating 1st contact rules for that space probe that infected a planet. Her rational was it was ultimately humans at fault so they were fixing something that was already broken by them.
Nah she stayed completely contradicting herself lol.
