Dave Bannion
Glenn Ford

Driven by a singular, obsessive need to avenge his wife's murder and dismantle the crime syndicate that destroyed his perfect life.

Driven by grief, he abandons protocol and operates outside the law, bringing unintentional ruin to those around him before pulling back from the brink of total moral darkness at the very end.
Debby Marsh
Gloria Grahame
Motivation
Initially motivated by greed and comfort, her motivation shifts entirely to visceral vengeance and a desire to redeem her compromised life.

Initially a shallow, materialistic gangster's moll who enjoys luxury and looks away from violence, Debby undergoes a profound transformation. After being brutally disfigured by her lover, she finds her conscience and turns into an avenging angel, sacrificing herself to finish the job Bannion's moral code prevents him from doing.
Vince Stone
Lee Marvin
Motivation
Motivated by a desire to maintain power and control through physical intimidation, violence, and loyalty to the syndicate.
Character Arc

Motivation
To protect his criminal enterprise, his immense wealth, and his socially respectable reputation at all costs.
