I mean, she knew it was something she didn't really like , and she didn't ask questions because she lost her taste for it...
But that's sorta like saying you're going to get some food, and I know your broke, and then I decide not to worry too much because I know you, but you killed a whole neighborhood.
I'm probably off, but given her reaction upon finding out the plan, I can't think she knew exactly what the plan was, especially given you specifically didn't want to know.
It was pretty much alot worse than she thought by several magnitudes.
And no one really seemed to give their exact reason for wanting her fired, aside from "Okay, you definately suck." after she goes "Millions of people dead..didn't like."
Also, I'd think some people would understand how she reacted to all this stuff, seeing as many of them are warriors, *and* human.
