Ron Weasley would do anything for his family. For instance, at age 12, he risks his life going down to the previously uncharted Chamber of Secrets to save his sister from clear and present danger. Not only is this an incredible example of Ron's bravery, but it's also a testament to the bond he has with his siblings. He constantly talks about his older brothers Bill and Charlie, especially about everything they've accomplished. He's clearly traumatized in the books when Percy denounces his family. He even wears the sweaters his mother knits for him even when he doesn't care for them. Ron cares about his family more than almost anything, and that clearly shows through his portrayal in the books and the movies.
