How do you describe Bob Ewell's personality?

He is a role player in 'To Kill a MockingbirdHarper Lee" . Bob Ewell is a drunken, mostly unemployed member of Maycomb's poorest family. In his knowingly wrongful accusation that Tom Robinson raped his daughter, Ewell represents the dark side of the South: ignorance, poverty, squalor, and hate-filled racial prejudice.
