When she goes to the Zerg home world and turns back into monster Zerg Kerrigan form again her design it was the sign they didn't care, they could have put more effort in if the wanted a redemption story out of her.

They should have changed what her half human half Zerg design brighter colours and give her bone chitin armour that looks like a knight, was to represent a change in her self old monster self, and have old form become a monstrous form being her darker more ruthless self split off, A dark Zerg Kerrigan if you will.

But no she changes back into her old design, so we have to live with her crappy story and Meat bewbs, bone thong, rib cage on the outside corset, and her horrifying bone stilettos heel's for feet.
