Even Picard broke the PD multiple times. If we are basing ethics on that then he’s no better.
In fairness, Picard is extremely upfront and honest that he has broken the Prime Directive in situations where he’s felt it would be callous not to.
Separately, he also said that while rules are a good thing, rules cannot be universally absolute.
Another thing he’s said is that Starfleet doesn’t want officers that will blindly follow orders, but rather to think about them seriously and weigh them in their minds.
Janeway straight up said to another captain that she’s never broken the Prime Directive in her life, despite clearly doing it a bunch of times. She’s in denial.
In fairness, Picard is extremely upfront and honest that he has broken the Prime Directive in situations where he’s felt it would be callous not to.
And he’s generally careful about trying to make sure that there is justification for breaking the Prime Directive before doing so.
He was particularly put out about being involved in Klingon political successsion because it would be a violation of the Prime Directive, and he’d be wading into Klingon business, with no justification for his being so, other than that he was appointed.
That’s my only real issue with her is her comment to the Nova class captain about it.
However, I give her the benefit of the doubt here because she’s clearly trying to encourage him that they don’t need to abandon their morality. If she tells him that she’s done it half a dozen times or so then he might be more likely to assume that’s the standard.
Now we all know in hindsight that he’d already committed an atrocity and wanted assurance from Janeway that he wasn’t alone in his decisions to prioritize crew over other sapient beings, but she was simply seeing the younger version of herself in him and attempting to assure him that he doesn’t have to give up hope and sink to those depths.
Voyager has more of a problem with character writing consistency than it does an issue with Janeway specifically, IMO.
Every captain in starfleet seems to treat it more like the Prime Suggestion.
