Hey Emily? You know Sokolov had people kidnapped off the streets to do experiments on with the Rat Plague, right? He wasn’t just some funny weirdo uncle, the man deserved to be put in the cage at the Hounds Pits pub. Corvo literally walks in on him denying life-saving treatment to some poor woman he also had in a cage.
At least Piero Joplin was contrite when you caught him peeping on Callista taking a bath.
