Yeah, I mean that Dean's comfortable killing anybody, pretty much – unless it's Sam (or Cas, or maybe Bobby). Had he counted Sam the way he does everybody else, Sam would have probably dies as soon as Dean found out he had powers, definitely by the time John said he might have to kill him, for sure by the time he was possessed by Meg.
Dean keeps getting more and more like that, until season 8. More comfortable killing people possessed, vessels etc. - killing just in case, etc.

What do you means by "goes away"? Dean's – perhaps discomfort – for not having killed Sam?

I like your point re Amy. And in that one, again – Sam was so very quick to forgive that... and if he expected Dean to lie to him and kill her anyway – it didn't show. He didn't tell her to run...

fuck morality, he's not killing his brother


But that's morality too. It's putting love, or loyalty, or "his people", or family over anything else he needs, wants, believes. That's a very strong conviction. If that's not a moral POV, it's because morality isn't a big/deep enough concept here, perhaps...

You could claim it's nothing but a strong emotional/psychological need, but I believe Dean really stands by it, believes it is the right thing to do.


Cas – huh, definitely. Aww...
