"either it knows better and it's smart and majestic and is choosing to kill people, or it doesn't, and it's not better than any other food." That is exactly my feeling on the matter. And frankly, I don't care whether the dragon is a murderer or just a beast. Either way, we're all better off without it hurting anyone else, and to kill it and not use the meat and bones and everything would be the most disgustingly wasteful thing I've ever heard of.
I don't much like it, either. It's why I believe in the Maker and still never go to the Chantry.
