Character mistake: When Jordan Kalfus is reading the instructions off the paper, the word divided is spelled 'devided'. (00:59:52)
Character mistake: The mother is supposed to be American, but she speaks in her native Australian accent near the end when she says, "I don't think I can take anymore of this" upon finding out that Pita may be alive.
Continuity mistake: After Creasy cuts off the first finger of the first man he kills, he is using the car cigarette lighter to stop the bleeding. When the shot changes to show him using the lighter, the man's finger is seen bent around the top of the steering wheel.
Answer: Creasy was a contract assassin for the CIA. His downfall was his drinking because it affected his reaction time and so forth. He had a lot of bad memories he was trying to live with. He considered this bodyguard assignment to be a blow off assignment. This and his bad memories combined with his drinking problem, made him severely depressed. This is why he considered killing himself. At the end of the movie, you see Creasy being taken away in a car. His gunshot wound from the "Voice's" brother, along with his prior gunshot wounds that were never properly treated, had finally gotten the best of him. He was bleeding the whole last half of the movie because he never fully recovered from the gunshot wounds. So, to answer the question of why he died, he bled to death.
