A re-write of the scene where Cas kills Bal, but from Cas' pov. Disclaimer: I don't own.

It was a waste, what you were about to do. An utter waste. And a shame. But it had to be done. To say it made you 'sad' was a bit of an overstatement, but it didn't exactly make you happy. He was a brother. A good brother. A friend. And he'd helped you out a lot in the past – you didn't really want to kill him. It wasn't just that he liked you – he loved you. He cared for you more than his own life, and you'd used that to your advantage – of course you had, who wouldn't? – you'd exploited him. He brought it upon himself really – he was so young, so impressionable, so easy to fool with kisses and touches and lies. He was a useful tool. He had such a way with words that you used to say he could charm the wings off an angel. He almost did once. But now you believe him to have outlived his usefulness. And not only that, but he betrayed you. He deserved to die.
So you summoned him. To his favourite place as one last, undeserved favour to the brother you were about to murder. You spoke to him – kind words at first, and then the harsh, jagged edges scratched through the sugar-coating. You let him know how disappointed you were with him. You let him know how much it 'hurt'. Not very much, admittedly, but who's to know that you played it up a little? What amuses you is that he thinks he is safe. No matter what you say to him, nothing can break through the haze of love and devotion to you which clouded his mind, which reassured him that you would never harm him. So he stood there, confident and proud in his last moments. And your face is blank as you flit behind him and thrust the blade through his waiting back.
He makes a sound, just a little one. It could easily have been mistaken for a gasp of surprise or pain, but you heard it for what it was. It was an question: 'Cas?'. That's all he said, but it conveyed everything. He felt betrayed by you. How very ironic. Your forehead wrinkled as you considered the problem: if you betrayed one who has betrayed you, is that a sin? You tilted your head to the side as you thought, but the conclusion you came to was that you were ridding the world of yet another traitor. So you were in the right.
You allowed yourself a brief glance down at the body by your feet, and you ran your fingers through the silky feathers, losing yourself in the simple pleasure of a soft touch. You couldn't bring yourself to regret, so instead, you launched yourself upwards. Looking down on the scene that you had inhabited only a moment ago, all that is left is the corpse of an angel and the faint rustling of black feathers in the wind.
