It would be awesome to have the option to bury those corpses for a chance of numen points or a rare curiosity. also, if you bury your own ancestor, it could become a "harvestable" tombstone for numen points and a curiosity (honor the ancestors?). may be, bury a corspe could unlock a new bulding , the chapel or church or praying stone.
maybe you could just loot them for bones, making the corspe disapear.
