Yuri's arc would've been great ... IF they didn't up and forget about "society has laws about murder and breaking these laws have consequences," thus rendering Yuri getting a LITERAL get out of jail free card when he saved the world from the Adephagos. Also, the game framed it in such a way that if Yuri DIDN'T kill those people, he was doing the WRONG THING. If they wanted a more gray morality, they would've given Ragul and Cumore families and children, which would have been more thought provoking - sure evil people are now dead, but children are now deprived of their father, wives of their husbands, etc. Instead it's pretty cut-and-dried, with Yuri escaping any consequences for his actions at all.
