Vizenor's Trickster

I have one issue with Vizenor, and I think most of the class agrees--the Trickster in the Tales is not necessarily/hardly ever not cruel or unkind.  Most of the Tricksters are cruel, in our moral sense.  Coyote tricks his wife and sleeps with his daughters (an unforgivable act), Iktomi kills his best friend (Stone Boy), Old Man Napi takes advantage of a limping Coyote, thinking he can trick him.
