She was absolutely between a rock and a hard place. You have a responsibility to get everyone home, but you can’t just dive straight in and strong arm your way to get there as fast as possible, both because that’s a shitty thing to do and because you’ll likely face consequences at the very least by starfleet when you get home, maybe by delta species who don’t like what you’re doing.
Honestly I don’t know a single person who has a negative thing to say about Janeway, except maybe she was too restrained sometimes.
How many of the crew, especially the Maquis, had nothing to return to and could have settled on one of the worlds they encountered? That said it’s a completely foreign society whose complications and nuances you couldn’t possibly be able to comprehend in the few weeks Voyager is within range.
Seska? I’m not aware of a crew member with that name. There was a Cardassian spy on board one of the ships, but… She’s no longer a concern.
