My idea involves how much money you make before the end of the game. If you make the set amount or above when the game ends, you win the good quarma. If you're under the required amount by the time the game ends, you're done.
I just think messing with the townsfolk is meant for fun. Stranger doesn't seem like the nice type from what I've seen, so I don't think being nice to the townsfolk has anything to do with quarma.
