Dean Winchester’s biggest mistake on “Supernatural” was unlocking the first seal of the Apocalypse by torturing other souls in Hell. In order to release Lucifer, 66 Seals of The Cage must be broken, and the first one requires a righteous man to spill blood in Hell. Distraught over Sam’s death, Dean makes a deal with a crossroads demon to bring him back, agreeing to die in one year. When the time comes, Lilith unleashes a hellhound that kills Dean and drags him to Hell.

His heinous violence resulted in the death of thousands and burdened him with immense guilt. Among Dean’s many mistakes on the show, this one stands out as the worst due to its ethical impermissibility and the catastrophic outcome.

Throughout the series, both Sam and Dean make a plethora of mistakes, but their special bond often leads to the most drastic ones.

Dean’s mistake of unlocking the first seal of the Apocalypse is a pivotal moment in the show, forever changing the course of the story. It highlights his flawed nature and the tragic consequences that come with putting his brother above all else.
