There Will Be Blood

Daniel adopts H.W. as a calculated business move rather than an act of compassion. After one of his workers dies in an accident, Daniel sees an opportunity to present himself as a family man to attract investors. Having a child with him makes him appear more trustworthy and stable, which helps secure financing for his drilling operations. This reveals Daniel's character as someone who uses personal relationships strategically for financial gain.

Early in his career, Daniel already demonstrates his ruthless nature by continuing to work despite his broken leg, showing he will do whatever it takes for wealth.

Daniel refuses to bless the well primarily as a display of power and defiance against Eli's religious authority. After the blowout that deafens H.W., Eli demands payment and confronts Daniel, insisting that Daniel's refusal to offer any blessing or acknowledgment of the church contributed to the disaster. By refusing, Daniel explicitly rejects Eli's influence and asserts that his industrial pursuits answer to no higher power, escalating their rivalry.

This confrontation establishes the central conflict between industrial capitalism and religious morality that will define the film's second half.

The blowout is an uncontrolled release of oil and gas from the well, a well-known risk in early oil drilling operations. In the film, the blowout occurs during the drilling process in Little Boston, causing an explosion that leaves H.W. deaf. While Eli blames Daniel's refusal to bless the well, the actual cause is mechanical failure due to pressure buildup, demonstrating the dangerous and unpredictable nature of oil extraction.

This tragedy marks the point where Daniel and Eli's conflict turns personal, as both men blame each other for the disaster.

The man claiming to be Daniel's half-brother Henry is a con artist who exploits Daniel's loneliness and desire for family connection. Daniel forms a genuine bond with him, even revealing his oil discovery locations. When Daniel discovers Henry is not his brother but rather a man who may have been sent by rival interests to steal his business secrets, Daniel kills him in a fit of rage, revealing both his volatility and his desperation for familial connection.

Henry's arrival during Daniel's troubled period in Little Boston exploits Daniel's emotional vulnerability, showing how his isolation makes him susceptible to manipulation.

Daniel kills Eli in a violent outburst driven by decades of accumulated resentment and psychological deterioration. When Eli, now a radio preacher, approaches the drunken Daniel to negotiate land rights, Daniel sees an opportunity for final retribution. The confrontation reignites old wounds, and Daniel attacks Eli with a bowling pin, murdering him in his private bowling alley. This act represents the culmination of their rivalry, where Daniel's pure hatred for Eli's moral righteousness finally explodes into violence.

Their conflict has been building since 1911 when Eli first demanded payment for the church, with each encounter intensifying their mutual contempt.

By 1927, Daniel has achieved immense wealth through his oil empire but has become increasingly isolated due to his alcoholism and destructive behavior. The humiliation of Eli's baptism, combined with the loss of meaningful relationships, including his adopted son H.W. who leaves to work in Mexico, has left Daniel alone in his massive mansion. His relentless pursuit of wealth has come at the cost of every genuine human connection, leaving him to drink alone in darkness.

Daniel's trajectory from ambitious prospector to isolated recluse follows the steady erosion of his humanity throughout the film.

H.W., having grown up deaf from the childhood blowout, eventually decides to leave Daniel and pursue his own life in Mexico. When he tells Daniel of his plans, Daniel reacts with brutal anger, attempting to physically prevent him. H.W. ultimately leaves and expresses relief that he does not share any part of Daniel's nature, indicating he has found independence and possibly peace away from his adoptive father's corrupting influence.

H.W.'s departure represents the final severing of Daniel's remaining family connection, leaving him completely alone.

Daniel submits to Eli's baptism as part of a strategic calculation to secure the land deal in Little Boston. Despite his contempt for Eli's religion, Daniel agrees to be baptized publicly to gain Eli's support for acquiring the property. However, the experience humiliates him deeply, as he must publicly renounce his non-belief while the community watches. This humiliation fuels Daniel's later hatred and creates the psychological breaking point that contributes to his complete moral collapse.

The baptism represents Daniel's willingness to compromise his principles for business gain, a pattern that will escalate throughout the film.

Eli demands $10,000 from Daniel as payment for the church's blessing and support in acquiring the oil rights on Sunday family land. As the local preacher, Eli views himself as a moral authority and believes Daniel's wealth comes with spiritual obligations. When negotiations fail, they settle on $5,000, but Eli feels further wronged when the well disaster occurs and Daniel refuses to acknowledge any spiritual responsibility, leading Eli to pursue revenge through various means.

Eli's initial demand establishes his character as someone who uses religious authority for financial gain, mirroring Daniel's own materialistic nature.

When Daniel whispers 'I'm finished' after killing Eli, he is expressing the completion of his destructive journey. Having achieved immense wealth but lost everything meaningful, his adopted son, his humanity, his only remaining adversary, Daniel is left in hollow isolation. The phrase signifies both his triumph over enemies and his complete spiritual and emotional depletion. He has won financially but lost absolutely everything else, leaving him entirely alone in his mansion.

This final moment encapsulates the film's thematic arc: the corrosive nature of unchecked ambition and the emptiness of material success.

Daniel and Eli become rivals because they represent fundamentally opposing worldviews that inevitably clash. Daniel embodies ruthless capitalism and industrial progress, while Eli represents religious moral authority. Their conflict escalates from a business dispute over church payments to a deeply personal vendetta, with each man viewing the other as morally corrupt. Their rivalry intensifies through mutual betrayals, Eli manipulates Daniel through religion, while Daniel uses his wealth to humiliation and ultimately murder Eli.

The film sets up their conflict from their first meeting, making their eventual violent confrontation feel inevitable.
