Wouldn't it be cool to see more NPCs having dark sides to them, even amongst the kin-folk? Maybe there could be quests added which involved you getting into disputes between villages or people, like stealing animals, destroying buildings, kidnapping or even murdering other villages unsuspiciously (all with appropriate loss of "karma", of course). Maybe Kullervo doesn't like Juha's loud mouth, and wants you to destroy his traps, or ruin the catch in his nets.
