Unfortunately Janeway was an inconsistent psychopath
I love this discription. It also begs the question; could another captain have brought Voyager home? I'd argue Janeway's psychopathy was what kept them alive. Essentially she spent the entire time in a state of emergency, and had to act accordingly. Tuvix (as hated as the episode is haha) was a great example. Boiled down, Voyager needed it's chief tactical officer and even Neelix, who showed usefulness multiple times, more than a new being who would leave the ship. Ethical or not, she consistently did what had to be done for the ship and crew. I'm not sure Picard's integrity would have kept them alive.
I've long suspected that the only chance the US, and the world, has is the incompetence of the Trump administration.
