Janeway had to choose between possibly getting one crewman killed or definitely the entire crew.
In that case, I think she made the right call, even without the 9,500 light year jump.
I assume this is directed at my post? I can't tell without a quote. This isn't what you said. You said:
"Kes was destabilizing the entire ship, which meant she was putting the lives of the entire crew in jeopardy. Even though it was totally accidental, Janewsy still has to safeguard the lives of her crew. Putting Kes on a shuttle did that, and she probably figured she could help Kes while still keeping her crew safe."
How does Janeway help Kes by giving her the shuttle, when it is more likely that she will destabilize the shuttle as she did to Voyager? I'm trying to understand your POV, that Janeway was helping Kes, but it seems like it would be more likely that Kes would destabilize the shuttle and die.
I suspect that the writers "painted themselves into a corner" with the plot line that Kes was involuntarily destabilizing Voyager. I suspect it was done for the spectacle, and in the end, they hoped no one would notice the giant plot hole they created... that she would probably involuntarily destabiize the shuttle, too.
