Despite her moral ambiguity, Kal'tsit makes it very clear in one of the epilogue scenes of "Grani and the Knight's Treasure" that she doesn't care about Skadi's or anyone's motivations for joining Rhodes Island as long as they follow the rules, because rules are extremely important, and she will not tolerate any blemishes on Rhodes Island's reputation. Additionally, Ansel notes she was visibly upset for the first time the day Kal'tsit brought Popukar to Rhodes Island, which is later revealed to be after rescuing her from her abusive slave owners, showing that whichever case it is, there's definitely a line of evil that's too far for her either way.
