"Hence they must see that they remain in the tribe. For them evil is essentially any offense that would break up their tribal status. There are two kinds of offenses: ethical and tribal. Ethical offenses include all aberrations committed consciously and which harm not so much the individual but others. Singbonga may punish such offenses by causing illness or misfortune to the tribe. (...) The offense against the tribe is the most tragic offense for the Sarna people, because their way to salvation is the tribe and this offense usually excludes them from the tribe." (p.52-53)"
