I had that bad feeling myself, recently. "This merchant is in an extremely dangerous place," I thought. "And here I am, overloading them with 39 scimitars and the equivalent contents of half a library and some dude's entire ribcage just so I can take a scroll off them. What happens if and when they have to run? They'll never make it. They'd have to ditch all of it just to have a chance."
So I just started stealing. It's for them. I'm out here saving lives, and not even needing your thanks. Just saying it would be nice.
