That are the Sadistic choice of Tactics Ogre(for that Matsuno was a genius), but in some fashion, Vyce is less 'forced'(read looks like a plot hole), maybe because both characther keep a façade of streght but have their crack inside.
In general Vyce as class and person worth(and mostly Law route teach more realities of war), but Catiua... well if a good ending was posible without her... a lot of people would choice it,XD
I don't entirely understand what I'm looking at here, but I do admire how you conveyed such thought-provoking emotion in each individual character. Makes me wonder what's going on. Your skill never seizes to amaze me.
