True, very true. But as far as the other angels they've encountered (Balthazar, Raphael, Michael, Zachariah, etc.), they weren't treated with respect because they were "dicks" as the Winchesters would put it (well, maybe not Michael, but I think you get my point.) As for Cas' possibly returning to make amends, I don't think any of my predictions would happen since Sera Gamble confirmed him dead: http://www.tvline.com/2011/10/supernatural-castiel-dead-alive-misha-collins/.

But, since this is Supernatural, I'm betting he might come back maybe near the end of the season and dead people come back pretty much all the time.
