They are only able to because of her. She points them in the right direction and most of the time they ignore her. They only want Lith back so much now because of what she showed them. She is guiding things in the proper direction from the background.
Lith gave so much just for being allowed to go back to fight a war that he didn't even need to truly participate, I really don't like the way Legion moved the plot, it's truly nonsensical.
