Yeah he definitely was an idiot. Instead of accepting her as she was and loving her that way, he wanted to reshape her into a version he found better. It wasn't just people's view that destroyed her, it was also his own. She obviously only accepted for him. She was content the way she was. It's sadly common with people who have loved ones with some kind of disability. Trying to make their life as "normal" as possible to conform to society when in fact they're only hurting that person more by giving it more importance in their lives.
