Darkness only affects people. Corrupts people's heart to get free by its own. But the choices always depend on the people. Rumple was never strong enough to resist the darkness, he embraced it  and accepted it. So is Emma. My theory is that Darkness wants to fill the people's hearts with evilness because for him, it's the only way to get free (except absurbing the darkness into the hat like the Apprentice did). So, with that way, the person inside that body will be gone and as I said, it will be free in the body of a Dark One.
