Romanoff Dukedom: Plan (3)

If Zarya died from her wound, Ius would quickly blame himself for it. 

Ius wasn't afraid of getting the blame. He was afraid that his actions he thought were for the better would only end up killing more innocent people. 

He didn't care whether Erwin's death would bring misfortune to others. If everything went according to plan, Erwin's bedeviled accomplices would encounter disorganization within their circle.
