The story involves Hex escorting a photographer through Apache country. Kiowas attack the Apaches and kill Hex's friend Yellow Bear. Hex goes after the Kiowa to kill their leader and avenge Yellow Bear.
The writers might argue that they put these words into the mouth of the photographer--that they accurately reflected the white man's opinion of Indians at the time. Maybe so, but it was the writers' choice to present only the white man's perspective. They could've added a scene where the photographer learns the Kiowa are real people, not cardboard props.
All in all, an average comic.
