"Kill with kindness," Castiel sighed, but not scornfully. He leaned back in his seat, lost in thought at the other's words. He knew there was still good in the world, even back in the two he'd left behind. He could see it, and could see the beauty in each. And of course, he knew all was still his Father's creation. That alone made it worth protecting, and had value in Castiel's eyes. He still couldn't understand how his brothers had become blind to it.
