Why did Ethan give land to Martin if he hates him for his heritage so much? There was never a moment that hinted towards him changing his mind.
He may or may not hate Martin (it seems by the way he dismisses the "whiteness" of captured women that his hatred of Native Americans is more towards their culture than their "race", but the point is a I have no niece towards Debbie, which he knows will infuriate Martin. Plus, he's the only one he can think of to leave his stuff to.
As the above entry notes, this is his way of broaching the subject to Martin that he's no longer trying to rescue Debbie. He means to kill her. It's really about her, not him.
