Every Supernatural fan remembers the whiplash. After the explosive, tear-jerking finale of Season 5—where Sam Winchester literally jumped into the fiery cage of Hell with Lucifer to save the world—the show had reached its natural conclusion. Creator Eric Kripke had told his five-year story arc. The Apocalypse was averted. Roll credits.
The line that defines the season comes from Castiel: "I'm not going to kill Dean. I'm going to kill you. You're the one who made him weak. You're the one who made him a soldier, who gave him orders, who turned him into a killer. I'm going to tear you apart, Michael, and I'm going to shove you back in your cage." supernatural episodes season 6
Yes, our beloved angel of Thursday is the big bad. Every Supernatural fan remembers the whiplash
This arc asks a brutal question: What makes Sam Winchester a hero? Is it his skills, or his empathy? The show argues it’s the latter. Soulless Sam is terrifying because he is a perfect hunter—and a perfect monster.

She doesn’t want to end the world; she wants to reclaim it for monsters. The Apocalypse was averted
