Great Character: Jules Winnfield (“Pulp Fiction”)
It’s easy to think of Jules in Pulp Fiction [screenplay by Quentin Tarantino, story by Quentin Tarantino and Roger Avary] as just some bad-ass tough guy, but in fact he’s the moral center of the story.

The IMDB plot summary:
The lives of two mob hit men, a boxer, a gangster’s wife, and a pair of diner bandits intertwine in four tales of violence and redemption.
One way of looking at the story is Jules [Samuel L. Jackson] and Vincent [John Travolta] are presented with a choice: Change or stay the same? Jules gets it… and Vincent doesn’t. As a result, one lives, one dies.
There are lots of indications that Jules is a thoughtful individual and Vincent is… well, Vincent.
Vincent: Want some bacon?
Jules: No man, I don’t eat pork.
Vincent: Are you Jewish?
Jules: Nah, I ain’t Jewish, I just don’t dig on swine, that’s all.
Vincent: Why not?
Jules: Pigs are filthy animals. I don’t eat filthy animals.
Vincent: Bacon tastes gooood. Pork chops taste gooood.
Jules: Hey, sewer rat may taste like pumpkin pie, but I’d never know ’cause I wouldn’t eat the filthy motherfucker. Pigs sleep and root in shit. That’s a filthy animal. I ain’t eat nothin’ that ain’t got sense enough to disregard its own feces.
Vincent: How about a dog? Dogs eats its own feces.
Jules: I don’t eat dog either.
Vincent: Yeah, but do you consider a dog to be a filthy animal?
Jules: I wouldn’t go so far as to call a dog filthy but they’re definitely dirty. But, a dog’s got personality. Personality goes a long way.
Vincent: Ah, so by that rationale, if a pig had a better personality, he would cease to be a filthy animal. Is that true?
Jules: Well we’d have to be talkin’ about one charming motherfuckin’ pig. I mean he’d have to be ten times more charmin’ than that Arnold on Green Acres, you know what I’m sayin’?
Jules is a violent man, but he has a moral code as we see in this memorable scene:

All boiling down to this defining moment:
Jules: I’m not giving you that money. I’m buying something from you. Wanna know what I’m buyin’ Ringo?
Pumpkin: What?
Jules: Your life. I’m givin’ you that money so I don’t have to kill your ass. You read the Bible?
Pumpkin: Not regularly.
Jules: There’s a passage I got memorized. Ezekiel 25:17. “The path of the righteous man is beset on all sides by the inequities of the selfish and the tyranny of evil men. Blessed is he who, in the name of charity and good will, shepherds the weak through the valley of the darkness, for he is truly his brother’s keeper and the finder of lost children. And I will strike down upon thee with great vengeance and furious anger those who attempt to poison and destroy My brothers. And you will know I am the Lord when I lay My vengeance upon you.” Now… I been sayin’ that shit for years. And if you ever heard it, that meant your ass. You’d be dead right now. I never gave much thought to what it meant. I just thought it was a cold-blooded thing to say to a motherfucker before I popped a cap in his ass. But I saw some shit this mornin’ made me think twice. See, now I’m thinking: maybe it means you’re the evil man. And I’m the righteous man. And Mr. 9mm here… he’s the shepherd protecting my righteous ass in the valley of darkness. Or it could mean you’re the righteous man and I’m the shepherd and it’s the world that’s evil and selfish. And I’d like that. But that shit ain’t the truth. The truth is you’re the weak. And I’m the tyranny of evil men. But I’m tryin’, Ringo. I’m tryin’ real hard to be the shepherd.
Jules has a choice: Shoot and kill Pumpkin and Honey Bunny, or let them go. He opts for the peaceful way out of the situation. As I said, Jules gets it. And Vincent?

I guess in his own way, he gets it, too.
Vincent is a fun character, but Jules is a fascinating and great one.
