Judge Turpin

Judge Turpin, also known as Lord Turpin, is the main villain of the 2007 British American horror film Sweeney Todd: The Demon Barber of Fleet Street. He is a corrupt judge who ruined the life of Sweeney Todd. He is portrayed by the late Alan Rickman, who also played Severus Snape in Harry Potter film series.

Personality
Judge Turpin is extremely evil, malevolent, cruel, sadistic, villainous and diabolical man. He is extremely deceitful, perfidious, dishonest and manipulative, as he ruined life of Sweeney Todd to rape his wife Lucy Barker. Despite his villainous acts, he is also highly elegant, polite and sophisticated. Destroying Sweeney Todd's life was his fatal weakness which led to his demise at the hands of his enemy.

Biography
Judge Turpin first appeared when he had Benjamin Barker arrested, due to his infatuation with Barker's wife Lucy Barker. He exiles Barker to Australia on false charges. Lucy is heartbroken, and becomes a recluse, never coming down from her home. Judge Turpin continuously pursues her, sending her flowers each day. He sends his right-hand named Beadle Bamford to summon her to his home, "blaming himself for her dreadful plight". At his house, during a masque ball, he drugs and rapes Lucy, who tries to kill herself by drinking poison, though she actually survives and is driven insane before being reduced to begging in the street.

Turpin then takes Barker's infant daughter Johanna Barker, and raises her as his ward. He keeps her locked away from the world and spies on her through a peephole in her wall. When Johanna turns 15, Turpin offers her his hand in marriage. She refuses, to which he seems baffled. When he spots Anthony Hope with Johanna, he threatens to kill him if he ever returns. We next see Turpin sentencing a child to hang for petty crimes.

On Bamford's advice, he goes for a shave at Sweeney Todd's barber shop, in order to impress Johanna — unaware that Sweeney Todd is in fact Benjamin Barker, returned from Australia and hell-bent on revenge. Todd is about to cut Turpin's throat when he is interrupted by Anthony, who reveals Johanna's plan to escape. Turpin promptly leaves, renouncing Todd's business. Turpin returns home and commits Johanna to an insane asylum, telling the owner Jonas Fogg that she is mad.

Turpin receives a letter claiming that Johanna has repented, and only wants his love. He is delighted and, following the direction of the letter, goes to Sweeney Todd's barber shop, where he is persuaded to have a shave. Turpin soon realizes Todd's true identity, and Todd savagely and mercilessly stabs him in the neck before slitting his throat. He then drops Turpin down the chute. Before he bleeds to death, Turpin grabs at Todd's accomplice Mrs. Lovett (Helena Bonham Carter) when she discovers him lying on her cellar floor.
