Savin has said that the only reason Amara's closer to Astra than any of her other kids is because Shade tracked her down and forced her to be a good sire. Kaede, on the other hand, was visited by her enough she knows her mother a) has a cock, and b) is (or at least appears to be) quite girly despite that (which encouraged Kaede to keep her own cock), but not enough to be surprised that she wouldn't visit her and Zeke for New Year's. Honestly, Amara could go either way depending on how into the role of Dread Lord she is, and whether she's willing to betray that for the sake of her kids.
That said, Shade appears to be a genuinely good person outside working with the Void - and given that we've only seen her work with them against other criminals who would (or at least should) be legitimate bounty targets in their own right (i.e. Kara), even that might not be a point against her.
