In a story of redemption, Jules' redemption is the biggest of all. A hitman (for quite a few years, we can assume) working for Marsellus Wallace, Jules, unlike Vincent, sees his job as more of a way of life, something he can't go home at night and leave the day at the office. When we first meet him, he's one his way to Brett's (who has stolen (?) a briefcase from Marsellus) with Vincent, his partner. After getting the briefcase and killing Brett (as well as a few others), a man who was hiding in the bathroom bursts out, firing six times at point blank range at Jules and Vincent. He misses with every shot, and Jules' life suddenly changes. Seeing it as divine intervention (meaning that God came down and stopped the bullets), Jules decides that it's a sign from God telling him to quit and go straight. It's his opportunity for redemption, and he takes it. He quits the lifestye, and we can assume he, as he says, "wanders the earth" for the rest of his life.
http://quentin-tarantino.8m.com/jules.htmAnton Chigurh is an emotionless, compassionless killing machine. His inability to comprehend human life is matched only by his ability to take it, as he does with ruthless abandon throughout the running of No Country For Old Men. Hired to track down drug money by a group of Americans, he quickly kills those who hired him and begins to search for the money on his own. He carries a cattlegun, which fires a cylinder from a hose which is connected to a tank of compressed air to destroy cylinder locks and dispatch a host of victims. He also carries a silenced assault shotgun. It is said that Anton Chigurh is now one of the most iconic villains of all time.
As for the victims who dont have some sort of reason to be dead behind them, he flips a coin to decide their fate.
Oddly enough, Chigurh is described as having his own set or morals, however twisted they may be. Anton does not kill at random or without purpose. Anton sees himself as a hand of fate; an instrument who exacts what is supposed to happen upon those it is supposed to happen to.
