I just about lost my mind when Chuck blamed the Darkness' release on Sam and Sam alone. Kind of like so many people blamed Lucifer's release on Sam and Sam alone, when then (as now) there were multiple factors leading up to that one act to include a lack of useful information on Sam's part.

Also, it reminded me that Chuck helped to goad Sam toward Lucifer's release. ("Does it all rest on my shoulders?" "It does look like the story's heading that way...")

And then finally claiming that Lucifer isn't a villain? No. Sorry. With everything that Lucifer did to Sam alone, which isn't even in dispute by anyone in universe, Lucifer is a villain.

I considered skipping this one. I wish that I'd considered a little harder.
