I think that the rape makes Jaime a much more complicated character and I actually rather like it. At the beginning of the series you hate jaime for being the piece of shit that pushed a child from a tower. Then, as the series goes on, you begin to like him as he starts to redeem himself. You understand his motives and can even begin to forgive him. Now he goes ahead and rapes his sister and suddenly he's not the misunderstood antihero he was before. Now the viewers are forced into a tricky situation where they're not sure whether they can actually say they "like" Jaime. This isn't a bad thing. It makes him much more interesting than he would have been had he been simply a misunderstood good guy.
