Is this the point of the story or something?
*GRRM Cackles quietly*
Yeah, that's been what I've thinking. I've been asking myself this since the first season, and nothing has changed my feelings on it yet.
Specific: Did Hodor need to die? It seems to me that Hodor's entire reason for being was unnecessary.
I haven't watched the show or read the books, but social media more or less exploded over the Hodor thing, so I had to look it up at the time. One thing I noticed in my research was that he doesn't die in the books. So I would say that at least GRRM didn't think he needed to die.
Not having read the books, I assumed the show was just farther along the storyline. Martin might not give Hodor the same end, but he could. I've heard of an encounter with him in an elevator that said as much.
