Monster: The Lizzie Borden Story uses a fictionalized version of Lizzie Borden's life to explore guilt, identity, public judgment and the idea of how “monsters” are made. The historical record is narrower: Lizzie was arrested in 1892, tried in 1893 and acquitted, while many relationships and private scenes shown in the series are inventions.
What Happens in the Netflix Finale
Episode 8, “Carnival,” moves beyond the trial and turns toward Lizzie's legacy. The finale also connects Lizzie and Bridget “Maggie” Sullivan with Aileen Wuornos in a symbolic sequence. Netflix's own ending explainer makes clear that this is part of the show's storytelling, not a historical event.
What History Records After the Trial
The Library of Congress records Lizzie's arrest on Aug. 11, 1892, the June 1893 trial and her acquittal on June 20, 1893. The historical record does not establish that Lizzie was responsible for the murders.
Lizzie and Emma
Lizzie and Emma lived together at Maplecroft for more than a decade after the trial. Current historical fact-checking places their major estrangement around 1904-1905, with Emma leaving in 1905 and no later reconciliation. Some confrontations shown in Monster are not supported by surviving evidence.
Nance O'Neil's Real Timeline
Netflix's own coverage notes that Lizzie met O'Neil after the trial, while the series places O'Neil in the trial storyline as a helper. The real friendship therefore cannot be used as evidence for the show's trial scenes.
Bridget's Story
Bridget Sullivan was the Borden household maid. Monster turns her relationship with Lizzie into a central romantic storyline, but reliable historical evidence does not establish that romance.
Why the Ending Is Different
Monster is scripted historical drama, not a documentary. Where the surviving record is incomplete, the creators build scenes and relationships to serve the season's themes. The ending should therefore be read on two levels: documented history and fictional interpretation.
Quick Answer
Was the Monster ending historically accurate? Only in its broad historical framework. Lizzie's arrest, trial and acquittal are documented; the finale's afterlife imagery and several relationship details are fictionalized.

Fact-check note
This article distinguishes the Netflix dramatization from documented history. Lizzie Borden was acquitted in 1893; claims about guilt, private relationships, motives and events not established by surviving records are described as fictionalized or disputed rather than settled fact.
