@KitsuneLet's just say that depending on what Kisa tells Moon Rider will affect the relationship between the employee and employer. Whether or not it's for better or worse depends entirely on how well or badly you handle the situation.
To put it simply: Dark Wraith hired Kisa to just be another weapon in Dark Wraith's arsenal. She expects Kisa to be useful and contractually loyal. If you can do better then that, then you will be rewarded justly.
@KoLWorking on it. Just need a few more logs into the fire.
As for the Sweepers, I won't lie: they were never meant to be good guys. Allies, sure, but not good guys. Morally speaking, they're only a little bit better then a group of friends who'd watch out for each other, in that they are also willing to punish each other if they go too far. But just because they're friends with each other doesn't mean they're friendly. They are a gang after all, only more organized thanks to the efforts of their leaders, and thus capable of doing bigger, more dastardly things with more sophistry then run-of-the-mill thuggery.
