* Exposure: His accomplice, Mrs. Lovett, unintentionally revealed his identity to the police, as well as his murderous actions, by sending a pie containing a victim's remains to a judge. This was a pivotal moment in the story.
* Confrontation: Judge Turpin, the man who unjustly imprisoned Todd and separated him from his family, became aware of the atrocities committed by the barber. A confrontation ensued in the barbershop.
* Revenge and Death: Todd, consumed by vengeance, engaged in a final, bloody confrontation with Turpin, killing him. However, he also was killed by his own daughter, Johanna, who had been raised by Turpin and was unaware of his true identity.
* Aftermath: Both Sweeney Todd and Mrs. Lovett met their end. The barbershop was destroyed, and the secret of their crimes was finally unveiled.
The specific details of Sweeney Todd's downfall vary slightly between the original 19th-century penny dreadful and the later adaptations, including the famous musical by Stephen Sondheim. However, the core elements of his exposure, confrontation with Turpin, and eventual death remain consistent.
