Comment: Obviously the intent was different in those cases. Demoski intentionally, repeatedly and viciously attacked the mushers. You cannot say he didn't intend to maim, if not kill, King and Zirkle. 

Bashore, Gross and Ellis were either distracted or under the influence and accidentally caused the death of another. They didn't get drunk, hop in a vehicle and intentionally chase people, circle them and try to run them over.
