As far as I am aware, not only OOC but lore-wise being committed of a crime in any of the city states, depending what it is, is dealt with sevre consequences. So there is also that aspect of the game you have to look at too. 
In Gridania, they have some of the most severe punishments of any city state. Which, is generally why the city is so peaceful.Â
I'd recommend summoning someone more of a lore expert of the city-state laws than myself for further information, but honestly  - if you arent willing to accept the lore consequences set by city states for your actions, it's probably best to  not A) Get caught. B) not play a villain.
