I own the addon personally - Too many NPC's can lag the server. However, you can set an amount of NPC's to exist according to the amount of players that are on. Also in regards to your original question, they won't walk around doing roleplay stuff but if you shoot a gun near them, they will run away and call the police. You'll see it on your screen, and if you walk into a "thug" or shoot at one, he'll run up to you and hit you (or shoot you if he's equip with a gun).
