And my main point was just that it's a needless change to the character that was written in the story. Again like I complained about not a change that needed to happen, just a change that happened because the writer of this episode of the show thought he could tell the story better than GRRM. A simple mindless change that shifts and transforms the whole mindset, motivations, and moral make up of a relatively major character.
Many of these changes have been actual storyline ideas that Martin himself thought of before going in a different direction with the books and has given his "blessing" when speaking with the writers extensively.
