Granted, she was an admiral - but did she ever have to face the consequences of her sometimes less than Starfleet-worthy decisions? I'd love to have read about that.
I'm so glad you said this, because I've been waiting for the right opening...
There's an argument to be made that she
has faced the consequences of "her sometimes less than Starfleet-worthy decisions," to wit, when she was killed. Because the circumstances of the events of
Before Dishonor, not to mention
Resistance, Greater than the Sum, and the
Destiny trilogy and its aftermath, are all
entirely a consequence of the actions taken by both iterations of Kathryn Janeway in "Endgame." The destruction of the transwarp hub is responsible for the series of events involving both the Borg who were cut off from the collective (and who killed Janeway) in
Resistance, Before Dishonor, and
Greater than the Sum, and the rest of the Borg's decision to, in essence, take out a hit on the Alpha Quadrant, resulting in at least 63 billion deaths.
And all that happened because Janeway decided that the needs of the one outweighed the needs of the many.
Mind you, I'm expressing neither support nor rejection of this argument -- for one thing, part of the fun is that it's one possible interpretation, and multiple interpretations are more fun than singular ones.

But it's a possibility worth examining, methinks.
