Each to their own, I guess, but I don't see the sadism of Yotsuyu and Misijia as being much different to that of the Warrior of Darkness and Scions at this point. Not after the deliberate and sustained physical and mental torture of a medic on the battlefield, cruelly cutting down her friends and comrades right in front of her as she begged for mercy. Not just once but twice - with ample opportunity to take her as a prisoner - and then in the final confrontation she is cut down like a rabid dog.
