My ps3 controller's r2 button gets stuck sometimes and i hit the guy accidently. I forgot about the vendor near the first bell tower who can de-hostile nps's so ended up killing the guy. To make it worse this made the silver armored npc (forget his name) in firelink shrine hostile towards me.
How much did i screw myself? I know Andrei does faith based upgrades, just wondering if im going to be missing out on any other items/upgrades etc.
