The threat this episode felt genuinely interesting and like a great way to explore a hunter's guilt, unlike the witnesses episode which indirectly did blamed the hunters for the victims they couldn't save, which wasn't fair at all. I also liked the way they left Sam's mistakes and his guilt behind in a way that didn't let him off the hook too easily and redeemed him properly, in my opinion. Sam as a witness and as a wannabe lawyer was a great way to accentuate the life he had before becoming a hunter with Dean. The (im)morality of killing criminals who already atoned for their sins was underutilized, but at least mentioned. Osiris was a fun, arguably neutral enemy.
However some things were ruined by the last 10 minutes of the episode. How come Jo became the executioner after Dean seemed to understand it was not his fault she died? Why not Amy or someone else? This episode was the perfect time to reveal Dean's secret and begin to resolve it, I don't understand why they chose a different episode for it when this one would have been so fitting.
I would give it an 8.5 if I could.
